Question

The length of a rectangular swimming
pool is 5 m more than two times its
breadth. Find the length and breadth
of the pool if its perimeter is 160 m.​

Answer 1

Answer:

l =55m and b =25m

Step-by-step explanation:

let the breadth of pool=X metre

then length of pool=2X+5 metre

perimeter=2(l+b)

160= 2(2X+5+X)

160=2(3X+5)

160=6X+10

160-10=6X

150=6X

X=150÷6

X=25 m

Therefore ,l=2X+5= 2×25+5 =50+5 =55m

b= X= 25 m.
