Question

Arectangularfield is 100m by 80m. Finh the ratio of:

a) length to its breadth b) breadth to its perimeter

Answer 1

Dear student,
to find the ratio of 2 quantities, all you have to do is to divide the first one with second.
(1) here it is asked for ratio of length to breadth
So we divide length by breadth.
Here ,length= 100m
Breadth=80m
Ratio= length/breadth
=100/80=10/8=5/4.
(2) breadth to it's perimeter
Perimeter=2×(l+b)
=2×(100+80)
=360
Ratio=breadth/perimeter
=80/360=8/36=2/9.
Thank you.
