Question

The perimeter of a rectangle is 240 cm and its length and breadth are in the ratio 5:3, find the area of the rectangle.​

Answer 1

Answer:

13500cm^2

Step-by-step explanation:

Let the length be 5x and breadth be 3x

5x + 3x=240

or, 8x= 240

or, x= 240/8

or, x=30cm

Length=5x

=5(30)

=150cm

Breadth= 3x

=3(30)

90 cm

Area of a rectangle =l*b

=150 cm * 90 cm

=13500cm^2
