Question

The length and the breadth of a rectangular school
playground are in the ratio 7:5. If the length of the
playground is 112 m, what is its perimeter?​

Answer 1

Step-by-step explanation:

let the ratio be 7x and 5x

Length=112

By question,

7x=112

x=16

Breadth=5x

5×16

80

Now,

Perimeter=2(l+b)

=2(112+80)

=384m

Answer 2

Let the ratio be 7x and 5x

Length=112

By question,

7x=112

x=16

Breadth=7x

5 x 16

80

Now,

perimeter=2(l+b)

=2(112+80)

=384m
