1)

L/B = 9:5 or L/B = 9/5 or 5L = 9B

Them L = 9B/5

Since the perimeter is 84, we have

L + L + B + B = 84

9B/5 + 9B/5 + B + B = 84

Solve for B = 15, then L = 27

Area = B X L = ?

2)

Call the sides length = 9x and breadth = 5x

L + L + B + B = 84

9x + 9x + 5x + 5x = 84

Solve for x = 3; then length = 3*9 = 27 and breadth = 3*5 = 15, then area = 27*15 = ?
