Question

The perimeter of a rectangular swimming pool is 154 metre its length is 2 metre more than twice its breadth what are the length and breadth of the pool

Answer 1

Step-by-step explanation:

let the length=2x+2

let the breadth =X

perimeter=154

2(2x+2+X)=154

4x+4+2x=154

6x+4=154

6x=150

X= 25

2x+2= 25×2+2

=52

length=52

breadth=25.

Answer 2

Step-by-step explanation:

l=2x+2

b=X

p=2(l+b)

154=2(2x+2+X)

4x+4+2x=154

6x+4=154

X=154-4

X=150/6

X=25

b=25

l=2x+2=25×2+2

l=52
