Question

The perimeter of a rectangle 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

Let the breadth be = x Then the length = 2x+2 Perimeter = 154m Perimeter =2 [l+b] 154= 2 [2x+2+x] 154=2 [3x+2] 154=6x+4 154-4=6x 150=6x 150/6=x X=150/6 X=26.6 X=breadth=25m Length = 2x+2= 52m

Answer 2

perimeter =154m
length = 2x+2

breadth=x

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

6x+4=154

6x=150

x=150/6

x=25

length=2(25)+2=50+2=52

breadth=x=25
