WebAgain, we need to do some subtraction: E – D / F – G is not indicated, but we have C – D and C – E. To work our E – D, we subtract C – E from C – D. 18 – 5 = 13 Area EDFG = 8 x 13 = 104 square inches. Finally, we add the two areas to work out the area of the irregular shape: 234 + 104 = 338 square inches.
