Question

A playground is in the shape of a rectangle find the perimeter of this rectangular playground whose length is twice of its breadth and area is 2048 square metre

Answer 1

let breath of the Field =x
then length =2x
area of square=(L×B)
2048=(x)(2x)
2048=2x²
x²=2048÷2
x²=1024
x=√1028
x=32

length =2x=2×32=64
breadth =x=32
perimeter =2(l+b)
perimeter =2(64+32)
perimeter =192meter
