Need To Find: The dimensions of the garden = ? Explanation: Let width = x And length be x + 4 Substituting this in equation(1), We get: x + x + 4 = 36 ➠ 2x + 4 = 36 ➠ 2x = 32 ➠ x = 16 Therefore, width is 16m and length is 16 + 4 = 20 m. $\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

Half the perimeter of a rectangular garden, whose length is 4 m more than its width, is 36 m. Find the dimensions of the garden.

Answer»

⠀⠀ıllıllı uoᴉʇnloS ıllıllı

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

Given:

HALF the perimeter of a rectangular garden = 36 m

➠ So, 2(l + b)/2 = 36

➠ (l + b) = 36 ……….(1)

The length is 4 m more than its width.

Need To Find:

The dimensions of the garden = ?

Explanation:

Let width = x

And length be x + 4

Substituting this in equation(1),

We get:

x + x + 4 = 36

➠ 2x + 4 = 36

➠ 2x = 32

➠ x = 16

Therefore, width is 16m and length is 16 + 4 = 20 m.

24.

The paint in a certain container is sufficient to paint an area of equal to 9.375 metre square. How many bricks of dimensions 22.5cm×10cm×7.5cm can be painted out of this container.

Answer»

$\huge{ \mathtt{ \purple{SOLUTION:-}}}$

Number of the bricks that can be painted out of the container = Area that can be painted by the container/SURFACE area of brick

Area that can be painted by the container =9.375m^2

$\large{ \implies{9.375 \times {100}^{2} {cm}^{2} }}$

$\large{ \implies{9.375 \times 10000 {cm}^{2} }}$

$\large{ \implies{93750 {cm}^{2} }}$

Total surface area of one brick = 2(lb+bh+hl)

$\small{ \implies{2(22.5 \times 10 + 10 \times 7.5 + 22.5 \times 7.5) {cm}^{2} }}$

$\small \implies{2(22.5 + 75 + 168.75) {cm}^{2} }$

$\small \implies{(2 \times 468.75) {cm}^{2} }$

$\small \implies{ \bold{937.5 {cm}^{2} }}$

No. of bricks that can be painted out of the container = Area that can be painted by the container/surface area of the brick

$\large{ \implies{ \frac{93750}{937.5}}}$

$\large{ \implies{ \frac{937500}{9375}}}$

$\large{ \implies{ \bold{100}}}$

Therefore,

100 bricks can be painted out by the PAINT.

After going 3/4 of my journey, I find that I havecovered 16 km. How much Journey is still left

Answer»

GivEn:

16 km DISTANCE covered in $\sf \dfrac{3}{4}$ of journey.

⠀⠀⠀⠀⠀⠀⠀

To find:

How MUCH journey is still LEFT?

⠀⠀⠀⠀⠀⠀⠀

SoluTion:

★ Let's Total Journey = x

⠀⠀⠀⠀⠀⠀⠀

★ Now, According to QUESTION,

⠀⠀⠀⠀⠀⠀⠀

16 km distance covered in $\sf \dfrac{3}{4}$ of journey.

⠀⠀⠀⠀

$:\implies\sf \dfrac{3}{4}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf x = 16 \times \dfrac{4}{3}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\sf{\red{x = \dfrac{64}{3}\;km}}}}}$

⠀⠀⠀⠀⠀⠀⠀

∴ Total Journey is $\sf \dfrac{64}{3}$

━━━━━━━━━━━━━━━

Therefore,

⠀⠀⠀⠀⠀⠀⠀

$\star\;{\boxed{\sf{Remaining \;journey = Total\; journey - Covered \;Journey}}}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf \dfrac{64}{3}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf \dfrac{64 - 48}{3}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\sf{\purple{ \dfrac{16}{3}\;km}}}}}$

$\therefore \sf \dfrac{16}{3}\;km$

If cosec x - secx = √5 then find cosecx + secx

Answer»

GIVEN : cosec x - secx = √5

To find : cosecx + secx

Solution:

cosec x - secx = √5

Let SAY

cosecx + secx = y

Adding both

2Cosecx = √5 + y

=> 2/Sinx = √5 + y

=> Sinx = 2/(y + √5)

2Secx = y - √5

=> 2/Cosx = y - √5

=> Cosx = 2/(y - √5)

Sin²x + Cos²x = 1

=> (2/(y + √5))² + (2/(y - √5))² = 1

=> 4((y - √5)² + (y + √5)² ) = (y - √5)² (y + √5)²

=> 4 ( y² + 5 -2√5y + y² + 5 + 2√5y) = (y² - 5)²

=> 8( y² + 5) = (y² - 5)²

=> y⁴ -18y² - 15 = 0

=> y² = (18 ± √(-18)² - 4(1)(-15) )/2

=> y² = (18 ± 8√6) )/2

=> y² = 9 ± 4√6

=> y² = 9 + 4√6 ( as Square can not be - ve)

=> y = √( 9 + 4√6 )

=> y = 4.3357

cosecx + secx = √( 9 + 4√6 ) = 4.3357

x = 17.718°
