Answer 1

Answer:

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?​

Step-by-step explanation:

length of the ground=7x

breadth=5x

Using unitary method:

7x=112

x=?

x*112=7x

x=112/7

x=16

breadth=5*16

=80m

perimeter=2(l+b)

=2*(112+80)

=2*192

=384m

perimeter of the playground is 384m
