Q.

Find the sides of a rectangle field whose perimeter is 90 cm and sides are in the ratio 5 : 4

Solution -

Let the sides of rectangle as 5x and 4x respectively, i.e Length (l) = 5x and breadth (b) = 4x

Perimeter of rectangle = 2 (l + b)

=> 2 (l + b) = 90 cm

=> 2 (5x + 4x) = 90 cm

=> 5x + 4x = 90/2 cm

=> 9x = 45 cm

=> x = 45/9 cm

=> x = 5 cm

Length = 5x = 5×5 cm = 25 cm

Breadth = 4x = 4×5 cm = 20 cm

Hence sides of rectangle are 25 cm and 20 cm.
