Remark
Break them into small figures: triangle, square ( I presume), and a parallelogram.
Triangle
Formula
A = 1/2 * b * h
Givens
b = 7
h = 4
Solve
Area = 1/2 b*h = 1/2 * 7 * 4 = 14
Square
Formula
Area = s^2
Solve
s = 7
Area = 7^2 = 49
Parallelogram
Formula
A = b*h
Givens
b = 7
h = 3
Solve
Area = 7 * 3
Area = 21
Total Area
Total Area = triangle + Square + Parallelogram
Total Area = 14 + 49 + 21 = 84 square yards.
