Step-by-step explanation:

Hello!
We have to use a certain formula to find the area of a parallelogram. The formula is:
A = bh
Since we already have the area and the base of the parallelogram, we will be able to find the height!
Notice how we multiply the base by the height to find the area? Well, we'll have to do the opposite to find one of its dimensions.
What's the opposite of multiplication? Division!
Formula for base:
B = A ÷ h
Substitute:
B = 60 ÷ 5
B = 12
ANSWER:
The base is 12 feet long.
