Question

the perimeter of rectangle swimming pool is 154m its length is 2 metre more than twice its breadth what are the length and the breadth of the pool​

Answer 1

Let breadth be b

perimeter =154 m

length =(2+2b)

perimeter = 2( l+b)

154 = 2(2+2b+b)

154 = 2(2+3b)

154 = 4+6b

6b = 154 - 4

6b = 150

b =150/6

b = 25

breadth = 25 m

length = 2+2b

= 2+2×25

= 2+50

= 52

length = 52 m
