Shape Area Formula Example Answer Rectangle A=b x h base=13 in

height=3 in39 sq. in. Triangle For whole number sides:

A = (b x h)/2

For mixed number or fraction sides:1/2 x b x h Ex. 1: base = 24 in and height = 10 in

Ex. 2: base = 1 1/2 in, height = 2 1/2 in1) 120 sq in.

2) 15/8 = 1 7/8 in.Trapezoid B = 6 in.

b = 4 in

h = 2 in.10 sq. in. Circle pi **·**r**·**r -or- pi**·**r^{2}radius = 4 in 50.24 sq. in.
