Answer:
10m
Step-by-step explanation:
Recall that the perimeter of a rectangle
= (2 x Long Side) + (2 x Short Side)
we are given that each of the long side = 20m and the perimeter is 60m
substituting these into the equation,
60 = (2 x 20) + (2 x Short Side)
60 = 40 + (2 x Short Side) (subtract 40 from both sides)
60-40 = (2 x Short Side)
(2 x Short Side) = 20 (divide both sides by 2)
Short Side = 20 / 2 = 10m
