Question

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

Answer 1

Answer:

The perimeter of a rectangle is 2(l+b) = 154

l = 2 + 2b

Substituting,

2(2 + 2b + b) = 154

4 + 6b = 154

b = 25

l = 52

Thus, the length is 52 m and the breadth is 25 m.

Answer 2

Step-by-step explanation:

let breadth of rectangle= x m

Then length of rectangle = 2x+2 m

Perimeter of rectangle= 2(l+b)

=2(2x+2+x)

154 =6x+4

150=6x

breadth=x=25m

length=2x+2=52m
