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) Â Â Â (subtract 40 from both sides)
60-40 = (2 x Short Side)
(2 x Short Side) = 20 Â (divide both sides by 2)
Short Side = 20 / 2 = 10m
Answer:
Sorry if this is wrong, but I didn't quite understand your wording. I'll answer the best I can!
Step-by-step explanation:
2 x (L + W)
2 x (20 + 10)
2 x 30
60
The answer is 10 meters.
