Question

Type the correct answer in the box.
The area of a trapezoid is calculated using the formula below, where A is the area of the trapezoid, b1 and b2 are the bases of the trapezoid, and h is the height of the trapezoid.

Rewrite the formula to find the base b2.

Answer:

  b2 = 2A/h -b1

Step-by-step explanation:

The usual formula for the area of a trapezoid is ...

  $A=\dfrac{1}{2}(b_1+b_2)h$

We can solve this for b2:

  $\dfrac{2A}{h}=b_1+b_2 \qquad\text{multiply by \dfrac{2}{h} }\\\\ \dfrac{2A}{h}-b_1=b_2 \qquad\text{subtract b_1 }\\\\ \boxed{b_2=\dfrac{2A}{h}-b_1}$

Answer 2

Answer:

2(\frac{Area}{h} ) - b1 = b2

Step-by-step explanation:The formula for calculating the area of a trapezoid is the following.

Area = \frac{b1+b2}{2} * h

What we are asked to find is the formula for finding b2. We can do this by rearranging the Area formula and getting b2 by itself on one side.
