Solve for b2 A=1/2(b_1+b_2)h

$A = \frac{1}{2} (b_{1} + b_{2}) h$

Step 1

Apply the distributive property.

$A = \frac{1}{2} \cdot (b_{1} h + b_{2} h)$

Step 2

Apply the distributive property.

$A = \frac{1}{2} (b_{1} h) + \frac{1}{2} (b_{2} h)$

Step 3

Multiply $\frac{1}{2} (b_{1} h)$ .

Combine $b_{1}$ and $\frac{1}{2}$ .

$A = \frac{b_{1}}{2} h + \frac{1}{2} (b_{2} h)$

Combine $\frac{b_{1}}{2}$ and $h$ .

$A = \frac{b_{1} h}{2} + \frac{1}{2} (b_{2} h)$

Step 4

Multiply $\frac{1}{2} (b_{2} h)$ .

Combine $b_{2}$ and $\frac{1}{2}$ .

$A = \frac{b_{1} h}{2} + \frac{b_{2}}{2} h$

Combine $\frac{b_{2}}{2}$ and $h$ .

$A = \frac{b_{1} h}{2} + \frac{b_{2} h}{2}$
