Answer:
12.54ftsq
(I made a lot of assumptions based on the information given)
Explanation:
I am assuming 4 is the hypotenuse because it is the longest.
Area of rhombus is side^2 but the lengths of the sides are different so i'm also assuming you mean a parallelogram
Area of a parallelogram is base*height
3.3ft*3.8ft=12.54ftsq
