9. Find the area of each figure to the nearest tenth.

1. Split the shape into a rectangle on the top and a trapezoid on the bottom. Find their areas separately and sum them. Area(rec)=110*50=5500 cm^2. Area(trap)=(110+180)*(140-50)/2=13050 cm^2. Area(total)=5500+13050=18550 cm^2.

2. Find the areas of the triangle and square separately, and sum them. Using Pythagorean's, DE=\sqrt(10^2-8^2)=6 ft. Area(ADE)=8*6/2=24 ft. Area(ABCE)=8*8=64 ft^2. Area(total)=24+64=88 ft^2.
