To solve for the area, find the area of an entire theoretical parallelogram. Then subtract the difference (the small triangle added).
Area = 1020 centimeters squared
If you need the answer in square feet, you have to convert.
(1 cm)^2 = (0.3937008 inches)^2
1 cm ^2 ≅0.155 in ^ 2 (or square inches)
A = 1020 * 0.155 ≅ 158.1 square inches
1 square inch = 0.006944444 square feet
158.1 square inches ≅ 1.097 square feet
