The ratio of length and breadth of a rectangle is 5 : 3 .If length is 8 m more than breadth, find the area of the rectangle.

Let length of rectangle = 5k
and breadth of rectangle = 3k
According to the quecation,
5k - 3k = 8
⇒ 2k =8
∴ k = 4
∴ Lenght = 5k = 5 x 4 = 20 m
Breadth = 3k = 3 x 4 = 12 m
∴ Required area = Lenght x Breadth
= 20 x 12 = 240 sq m
