To calculate the area of this parallelogram first you have to solve 18 to the power of 2. If you look at point A you see it says 45 degrees. So it should subtract 180 from the 45 degrees to get your total angle degrees. After that you multiply to find your answer

ABE is a 45 45 90 right triangle

ratio of leg: hypo = a: a√2

Given hypo AB = 18√2 so leg AE = EB = 18

Area of parallelogram = bh where b = 28 and h = EB = 18

so A = 28 x 18 = 504

Answer

A = 504 square units.
