Question

The length and breadth of a rectangular park are in the ratio 5:3 and it's perimeter is 192 m. Find the area of the park and explain how to solve.

Answer 1

Let length be 5x and breadth be 3x
So the perimeter is 2(l+b)
Which is
$2(5x + 3x) = 192 \\ x = 192 \div (10 + 6) \\ x = 12$
So the length and breadth are 60 and 36

so the area is 60*36 equals 2160

Answer 2

Let length be 5x and breadth be 3x
So the perimeter is 2(l+b)
Which is
$2(5x + 3x) = 192 \\ x = 192 \div (10 + 6) \\ x = 12$
So the length and breadth are 60 and 36

so the area is 60*36 equals 2160
