A park square in shape has a 3 metre wide road inside it running along its sides. The area occupied by the road is 1764 square metres. What is the perimeter along the outer edge of the road?

Read Solution (Total 1)

let x be length of side of inner square
let y be length of side of outer square
then
y^2-x^2=1764..........(1)
(y/2)-(x/2)=3.............(2)
solving 1 and 2
find y and x
the perimeter of outer square is 4y which is equal to 600 meter-sqaure.
