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

240 m²

The ratio of length and breadth = 5 : 3.

We know that,

Area of rectangle = length × breadth

= length of rectangle = 5a, breadth of rectangle = 3a

= 5a – 3a = 8

= 2a = 8

x = 4

length of rectangle = 5a = 5 × 4 = 20 m

breadth of rectangle = 3a = 3 × 4 = 12 m

Then, area of rectangle = length × breadth

= 20 ×  12 = 240 m²
