Answer:
[tex]a=\frac{1}{2}b_1h+\frac{1}{2}b_2h[/tex]
Step-by-step explanation:
We are given that an equation
[tex]a=\frac{1}{2}(b1+b_2)h[/tex]
Base length of sides of trapezoid=[tex]b_1, b_2[/tex]
Height of trapezoid=h
It can be used to determine the area of trapezoid.
Because area of trapezoid=[tex]\frac{1}{2}(b_1+b_2)h[/tex]
We have to find the equation which is equivalent to given equation .
Expand the given equation
[tex]a=\frac{1}{2}b_1h+\frac{1}{2}b_2h[/tex]
Hence, it is equivalent to given equation.
[tex]a=\frac{1}{2}b_1h+\frac{1}{2}b_2h[/tex]
