Question

FIND THE HEIGHT OF THE TRAPEZOID A =80 CM2 7CM 9cm what is H

Answer 1

`\text{Area = }\frac{(B\text{ + b) }\cdot\text{ a}}{2}`

B = 9

b = 7

A = 80

a = ?

Substitution

`\begin{gathered} \text{ 80 = }\frac{(9\text{ + 7)}\cdot a}{2} \\ \text{ 80 = }(16a)/(2) \\ \text{ 80 = 8a} \\ \text{a = }(80)/(8) \\ a\text{ = 10 cm} \end{gathered}`

The height of the trapezoid is 10 cm
