Question

The formula A = (1/2)bh represents the area of a triangle where A represents the area, b is the base of the triangle and h is the height of the triangle. 1. Solve this formula for b. 2. Show your work and explain each step.

Answer 1

Answer:

$b=\frac{2A}h$

Step-by-step explanation:

You first multiply both sides by 2 (if two quantities are the same, double the quantities will be the same).

$2A = bh$

Then, as long as the height of the triangle isn't zero, you divide both sides by h

$\frac{2A}h = b$ Reading right to left gives you the result

Answer 2

Answer:

The value of the formula for b is $b=\frac{2A}{h}$.

Step-by-step explanation:

Consider the provided formula.

$A = \frac{1}{2}bh$

We need to solve the formula for b

Multiply both the sides by 2.

$2A =2\times \frac{1}{2}bh$

$2A =bh$

Now divide both the sides by h.

$\frac{2A}{h} =\frac{bh}{h}$

$\frac{2A}{h} =b$

$b=\frac{2A}{h}$

Hence, the value of the formula for b is $b=\frac{2A}{h}$.
