AC = 8.9 BC = 6.5 (90% angle) 8.9 x 6.5 = <span>57.85 57.85/2 = 28.925 Area of ^ABC = 28.925 cm squared
DE = 55.1 55.1/ 11.02 = 5 DEF is 5 times as big as ABC DF = 44.5 FE = 32.5 44.5 x 32.5 = 1446.25 1446.25/2 = 723.125 I am not positive but I believe DEF = 723.125 cm squared Good Luck on the Test!! :D
