Question

The sides of a rectangle are in the ratio 7:5 and its perimeter is 96 cm. The length of rectangle is
(a) 21 cm
(b) 28 cm
(c) 35cm
(d) 14 cm​

Answer 1

Answer:

Sides of the rectangle in the ratio =7:5

Perimeter =2(l+b)=96 cm

Hence, Length + Breadth =96/2

=48 cm

Let length be =7x

Breadth be =5x

7x+5x=48

12x=48

x=48/12

x=4

Length of the rectangle =7x

=7×4

=28 cm

Answer 2

Answer:

The length of the rectangle is 28cm
