The other parallel side is 44 m
Step-by-step explanation:
Let us revise the formula of the area of a trapezium
, where
and
are its parallel bases
- h is its height (The distance between the two parallel bases)
∵ The area of a trapezium is shaped field is 480 m²
∴ A = 480 m²
∵ The distance between two parallel sides is 15 m
∴ h = 15 m
∵ One of the parallel side is 20 m
∴ = 20 m
We need to find
Substitute all these value in the rule of the area below
∵
∴
- Multiply the two sides by 2
∴
- Divide both sides by 15
∴
- Subtract 20 from both sides
∴
The other parallel side is 44 m
