Question

The perimeter of a rectangular swimming pool is 154m. It’s length is 2m more than twice it’s breadth. What are the length and the breadth of the pool

Answer 1

Answer:

106

Step-by-step explanation:

Let breadth be 2x

Perimater=2(l+b)

154=2(2+2x)

154=4+4x

4x=154-4

4x=150

x=150/4

x=35

breadth=2x

2×35=106

Answer 2

Answer:

2(l+b)=154m.

l=2b+2

let breath be b.

2(2b+2+b)=154m.

6b-4=154m

b=25m

l=2×25+2=52m.
