Answer:
l:b=5:3
perimeter=2(l+b)
=2(5x+3x)
=2(8x)
=16x=48m
=x=48/16=3.l=5×3=15m,b=3×3=9m
area=l×b
=15×9=135m^2.

Answer:
let 5x and 3x be as length and breadth respectively
perimeter = 48 m
So,5x+3x+5x+3x = 48
16x = 48
x = 48/16
x = 3
therefore, length = 5 * x = 5 * 3 = 15 m
Breadth = 3 * x = 3 * 3 = 9 m
