Area of a Trapezoid can be defined by:
A = [tex] \frac{1}{2} ( b_{1} + b_{2} )(h)[/tex] just substitute given information
[tex]8.1 = .5( b_{1} +6.7)(1.5)[/tex]
8.1 = .75(b₁ + 6.7)
8.1 = .75b₁ + 5.025
8.1 - 5.025 = .75b₁
3.075 = .75b₁
[tex] \frac{3.075}{.75} = b_{1} [/tex]
4.1 = b₁
the other base is equal to 4.1
