Challenge: (A question like this could be an extra credit question.)
A bulletin board is shaped like a trapezoid. If the bases are 45cm and 65cm and the height is 40cm, what is the area?
A=(b1+b2)h

Super Duper Challenge:(Don’t worry this type of problem is not on the test.)The area of a trapezoid is 48in2. The height is 4in. The measure of b2 is 3 times greater than measure of b1. Find the measure of each base.
A=.5(b1+b2)h48=.5(x+3x)448=2(x + 3x)48=2x +6x48=8x8 8h=6 in.
b1=6 in.b2=18 in.
