3.	The width of a rectangle is 16cm. If the perimeter of the rectangle is 80cm, find its length and its area
Answer» $\huge\underline\mathrm{SOLUTION:-}$ Given: The width of a RECTANGLE is 16cm. The perimeter of the rectangle is 80 cm. Need To Find: Length of the rectangle =? Area of the rectangle =? ExPlanation: The width of a rectangle is 16cm. [Given] The perimeter of the rectangle is 80 cm. [Given] We KNOW that: Perimeter of the rectangle = 2 ( length + breadth) 1st Case: We have to find the length of the rectangle, So, Let the length of the rectangle be x. As we know that, Perimeter of the rectangle = 2 ( length + breadth) Substituting the values in the above formula, we get, ➠ 2 ( L + b ) = 80 ➠ 2 ( x + 16 ) = 80 ➠ x + 16 = 80 / 2 ➠ x + 16 = 40 ➠ x = 40 - 16 ➠ x = 24 Now, We know that the value of x = 24. THEREFORE, length of the rectangle = 24 cm. $\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$ 2nd Case: We have to find the Area of rectangle, It is Given that, Breadth of the rectangle = 16 cm. Length of the rectangle = 24 cm Now, We know that, Area of rectangle = Length × Breadth Substituting the values in the above formula, we get, = 24 × 16 = 384 Therefore, Area of the rectangle = 384 cm². $\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

3.

The width of a rectangle is 16cm. If the perimeter of the rectangle is 80cm, find its length and its area

Answer»

$\huge\underline\mathrm{SOLUTION:-}$

Given:

The width of a RECTANGLE is 16cm.
The perimeter of the rectangle is 80 cm.

Need To Find:

Length of the rectangle =?
Area of the rectangle =?

ExPlanation:

The width of a rectangle is 16cm. [Given]
The perimeter of the rectangle is 80 cm. [Given]

We KNOW that:

Perimeter of the rectangle = 2 ( length + breadth)

1st Case:

We have to find the length of the rectangle,

So,

Let the length of the rectangle be x.

As we know that,

Perimeter of the rectangle = 2 ( length + breadth)

Substituting the values in the above formula, we get,

➠ 2 ( L + b ) = 80

➠ 2 ( x + 16 ) = 80

➠ x + 16 = 80 / 2

➠ x + 16 = 40

➠ x = 40 - 16

➠ x = 24

Now, We know that the value of x = 24.

THEREFORE, length of the rectangle = 24 cm.

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

2nd Case:

We have to find the Area of rectangle,

It is Given that,

Breadth of the rectangle = 16 cm.
Length of the rectangle = 24 cm

Now,

We know that,

Area of rectangle = Length × Breadth

Substituting the values in the above formula, we get,

= 24 × 16

= 384

Therefore, Area of the rectangle = 384 cm².

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

Answer» LET breadth be ( x ) cm and LENGTH be ( x + 7 ) cm *Area of rectangle = length breadth* Hence, Area of this rectangle = x( x + 7 ) cm^2 When, length is decreased by 4cm i.e. ( x + 7 - 4 ) = ( x + 3 ) cm Breadth is increased by 3 cm i.e. ( x + 3 ) cm Area becomes = ( x + 3 )( x + 3 ) GIVEN that area remains same, $\rightarrow x( x + 7 ) = ( x + 3 )( x + 3 ) \\ \\ \rightarrow x^2 + 7x = x^2 + 9 + 6x \\ \\ \rightarrow 7x = 9 + 6x \\ \\ \rightarrow 7x - 6x = 9 \\ \\ \rightarrow x = 9$ According to the SOLUTION, Breadth of ORIGINAL rectangle = x = 9 cm Length of original rectangle = ( x + 7 ) = ( 9 + 7 ) = 16 cm

30.

the length of a rectangleexcced it's breadth by 7cm. If the length decreased by 4cm and the breadth is increased by 3cm,the area of the new rectangle is the same as the area of the original rectangle. Find the length and the breadth of the original rectangle.

Answer»

LET breadth be ( x ) cm and LENGTH be ( x + 7 ) cm

Area of rectangle = length breadth

Hence,

Area of this rectangle = x( x + 7 ) cm^2

When, length is decreased by 4cm i.e. ( x + 7 - 4 ) = ( x + 3 ) cm

Breadth is increased by 3 cm i.e. ( x + 3 ) cm

Area becomes = ( x + 3 )( x + 3 )

GIVEN that area remains same,

$\rightarrow x( x + 7 ) = ( x + 3 )( x + 3 ) \\ \\ \rightarrow x^2 + 7x = x^2 + 9 + 6x \\ \\ \rightarrow 7x = 9 + 6x \\ \\ \rightarrow 7x - 6x = 9 \\ \\ \rightarrow x = 9$

According to the SOLUTION,

Breadth of ORIGINAL rectangle = x = 9 cm

Length of original rectangle = ( x + 7 ) = ( 9 + 7 ) = 16 cm

Answer» So LET the ratio be expressed as 10 x : 9 x : 7 x So 10 x + 9 x + 7 x = 364 26 x = 364 => x = 364 / 26 => x = 14. So Roshan = 10 x => 10 * 14 = Rs. 140 Binny = 9 x => 9 * 14 = Rs. 126 Elle = 7 x => 7 * 14 = Rs. 98

45.

Roshan, binny and elle are giveen rs. 364.They decided to divide the money in the ratio of 10:9:7. How much does each receive

Answer»

So LET the ratio be expressed as 10 x : 9 x : 7 x

So 10 x + 9 x + 7 x = 364

26 x = 364

=> x = 364 / 26

=> x = 14.

So Roshan = 10 x => 10 * 14 = Rs. 140

Binny = 9 x => 9 * 14 = Rs. 126

Elle = 7 x => 7 * 14 = Rs. 98
