Answer:
The height of the parallelogram is 20m
Step-by-step explanation:
Given the area of a parallelogram
A = bh where;
b is the base and h is the height
If the base and height of a parallelogram are in the ratio of 6:5. It's area is 480 inches, this means that b/h = 6/5
5b = 6h
b = 6h/5
Substituting equation 1 into the volume if the parallelogram we have;
A = 6h/5×h
480 = 6h²/5
6h² = 480×5
6h² = 2400
h² = 2400/6
h² = 400
h = √400
h = 20m
