Question

The sides of rectangular park are in ratio 3:2 If it area is 1536 m2 find the cost for fencing

Answer 1

Let the sides be 3a and 2a

Area of rectangular park = length x breadth

3a x 2a = 1536
6a² = 1536
a² = 256
a = 16 m

Length = 3 x 16 = 48 m
Breadth = 2 x 16 = 32 m

Answer 2

Let the sides be 3x and 2x

Area of rectangular park = length x breadth

3x x 2x = 1536
6x² = 1536
a² = 256
a = √256 m
a = 16 m

Length => 3 x 16 = 48 m
Breadth => 2 x 16 = 32 m
