What is the area of the figure?
a.
256 square inches
b.
288 square inches
c.
320 square inches
d.
384 square inches

The answer is a. What you need to do is find the area of the shape if it were a perfect rectangle - (20)(16)=320 in^2. Next you make an imaginary square in the corner (it's a square because it's 8in by 8 in) and find the area - 8^2 or (8)(8)=64. Finally you subtract the values - 320 - 64 = 256 in^2 voila.

J= r + 9 because since jessica rode 9 more miles than roger, you add 9 miles to rogers mileage.
