Answer:
h = 5.488 in
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
If we consider the base as 9.8 and h as 5.6 then
A = 9.8 × 5.6 = 54.88 in²
If we consider the base as 10 with perpendicular height h then
10h = 54.88 ( divide both sides by 10 )
h = 5.488 in
