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

Set up a proportion
90/x = 60/100
60x = 9000
x = 150
if you're wondering why I used 60 instead of 40 in the proportion it is because $90 is 60% of the original price, not 40%
hope this helps!
