Question

The perimeter of a rectangular swimming pool is 154m.It length is 2m more than twice its breath.What are the breath of the pool?​

Answer 1

❇️ Given

Perimeter = 154 m

Length = 2m + 2 (breadth)

❇️ To find

Area = ?

❇️ Solution

Let breadth be x

Length = 2 + 2x

$\fbox\blue{Perimeter~=~2(l+b)}$

So,

154 = 2 ( 2 + 2x + x )

2 ( 2 + 3x ) = 154

4 + 6x = 154

6x = 154 - 4

6x = 150

$x = \frac{150}{6}$

x = 25

So, Breadth = 25 m

Length = 2 + 2 (25)

Length = 2 + 50

Length = 52 m

.°. Breadth = 25 m

Answer 2

Answer:

Let breadth be x

Length = 2 + 2x

$\fbox\blue{Perimeter~=~2(l+b)}$

So,

154 = 2 ( 2 + 2x + x )

2 ( 2 + 3x ) = 154

4 + 6x = 154

6x = 154 - 4

6x = 150

$x = \frac{150}{6}$

x = 25

So, Breadth = 25 m

Length = 2 + 2 (25)

Length = 2 + 50

Length = 52 m

.°. Breadth = 25 m
