Question

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

Answer 1

Answer:

p=154m

l=2+2b....A/c

p=2(l+b)

=2(2+2b + b)

=4+6b

154-4=6b

150=6b

b=25m

therefore l=2+50

l=52m

hope it helps

Answer 2

Answer:

The length of the pool is 52 m and breadth is 25 m.

Step-by-step explanation:

Let the breadth of the pool be x m.

Then, the length of the pool = 2x + 2 m

Perimeter = 2(l + b)

=> 154 = 2(2x + 2 + x)

=> 154 =2(3x + 2)

=> 154 = 6x + 4

=> 6x = 154 – 4

=> 6x = 150

=> x = 150/6

=> x = 25

Length of the pool = 2x + 2 = 2 * 25 + 2 = 50 + 2 = 52 m

Breadth of the pool = 25 m

Hence, the length of the pool is 52 m and breadth is 25 m.
