Question

The length and breadth of a rectangular park are in the ratio 5:3 and its perimeter is 128m. Find the area of the park

Answer 1

let the length and breadth is 5x and 3x
then,
2(5x+3x) equal 128m
10x+6x equal 128m
16x equal 128m
x equal 128/16
x equal 8m
then, 5x equal 5multiply by 8 equal to 40
3x equal 3 multiply by 8equal to 24
then, length and breadth are 40m,24m respectively.
