Question

The sides of a rectangle are in the ratio of 12:17:25 and it's perimeter is 540cm . find its area .​

Answer 1

Answer:

in this question given three sides ratio but we will take here first two ratio because we know that the sides ratio of rectangle is of two terms

let the total ratio of the sides are.

then yhe sides are 12x and 17x

perimeter =540cm

2(12x+17x)=540

2(29x)=540

58x=540

x=540/58

x=9.4

then sides are 12*9.4 and 17*9.4

112.4 and 159.8 cm

The Area = length * breath

=112.4*159.8

=17961.52cm2
