38.	Sides of a triangle are in the ratio of 3: 5: 7 and its semi perimeter is 60 cm. Find its area.
Answer» Answer: The Area of the Triangle is $240\sqrt{3}$ cm². Step-by-step explanation: Given:- Sides of the triangle are in the ratio of 3: 5: 7 . Its SEMI perimeter is 60 cm. ∴ The perimeter of the Triangle will be=60×2=120 cm. To FIND:- The area of the Triangle. Things to Remember:- In geometry, the semi-perimeter of a Triangle is half of its perimeter. Formula Applied:- Perimeter of Triangle= Sum of all of its Sides. Solution:- LET the sides of the Triangle be 3X, 5X and 7x. Now, We know that Perimeter of Triangle = Sum of all of its Sides ⇒120=3x+5x+7x ⇒120=15x ⇒ $x=\frac{120}{15} cm$ ⇒ x= 8 cm ∴ The sides of the triangle will be 24 cm, 40 cm, 56 cm. S= $\frac{a+b+c}{2}$ = $\frac{120}{2}$ =60 cm Area of the Triangle ⇒ $\sqrt{s\times(s-a)\times(s-b)\times(s-c)}$ where a=24, b=40, c=56 ⇒ $\sqrt{60\times(60-24)\times(60-40)\times(60-56)}$ ⇒ $\sqrt{60\times36\times20\times4}$ ⇒ $10\times2\times6\times2\sqrt{3}$ ⇒ $240\sqrt{3}$ cm²

Sides of a triangle are in the ratio of 3: 5: 7 and its semi perimeter is 60 cm. Find its area.

Answer»

Answer:

The Area of the Triangle is $240\sqrt{3}$ cm².

Step-by-step explanation:

Given:-

Sides of the triangle are in the ratio of 3: 5: 7 .

Its SEMI perimeter is 60 cm.

∴ The perimeter of the Triangle will be=60×2=120 cm.

To FIND:-

The area of the Triangle.

Things to Remember:-

In geometry, the semi-perimeter of a Triangle is half of its perimeter.

Formula Applied:-

Perimeter of Triangle= Sum of all of its Sides.

Solution:-

LET the sides of the Triangle be 3X, 5X and 7x.

Now, We know that

Perimeter of Triangle = Sum of all of its Sides

⇒120=3x+5x+7x

⇒120=15x

⇒ $x=\frac{120}{15} cm$

⇒ x= 8 cm

∴ The sides of the triangle will be 24 cm, 40 cm, 56 cm.

S= $\frac{a+b+c}{2}$ = $\frac{120}{2}$ =60 cm

Area of the Triangle

⇒ $\sqrt{s\times(s-a)\times(s-b)\times(s-c)}$ where a=24, b=40, c=56

⇒ $\sqrt{60\times(60-24)\times(60-40)\times(60-56)}$

⇒ $\sqrt{60\times36\times20\times4}$

⇒ $10\times2\times6\times2\sqrt{3}$

⇒ $240\sqrt{3}$ cm²

40.

Find the area of the shaded part, if the side of the square is 8 cm and the circumference of circle is 44 cm

Answer»

Answer:

side of square(a) = 8cm

AREA of square = a∧2 = 8∧2 = 8×8 = 64cm∧2

circumference of circle = 2πr = 44cm

2πr = 44

2 × 22/7 × R = 44

2 × r = 44×7/22

2r = 14

r = 14/2 = 7cm

area of circle = πr∧2 = 22/7 × 7×7 = 154cm∧2

Area of SHADED region = area of circle - area of square

= 154 - 64 = 90cm∧2

AREA = 90cm∧2

hope this helps.

Answer»

Step-by-step explanation:

GIVEN that:

To find a hidden PICTURE by plotting and joining the various points with given coordinates in a plane.

(a) draw coordinate axes x and y on graph keeping mind of values to be ploted.

Solution: Plot horizontal line and a vertical line , INTERSECTION of both lines is origin.

Horizontal line is X-AXIS

Vertical line is Y-Axis

Mark points on the graph.

(b) Plot the points given in alphabetical order and join them.

Solution: According to the given points A(1,3),B(-2,2), C(-4,1), D(-5,0), E(-4,-1), F(-2,-2), G(1,-3), H(8,0), I(11,-3),J(10,0), K(11,3), L(8,0), M(2,2) & N(3,4),(draw an eye on (-3,1))

(As SHOWN in attachment)

(c) join last point N with first point A.

Solution: Join all points in alphabetical order and last point to the first one.

put eye on (-3,1)

After joining all these points a fish shape appeared as shown in attachment.
