Question

solve the area of a triangle formula for the variable ( b ): ( a=\frac{1}{2} b h ) note: in this formula, ( a = ) area, ( h = ) height, and ( b = ) base. ( b=\frac{2 a}{h} ) ( b=\frac{a}{2 h} ) ( b=\frac{a h}{2} ) ( b = 2 a h )

Explanation:

Step1: Multiply both sides by 2

$$2A = bh$$

Step2: Divide both sides by h

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

Answer:

$b = \frac{2A}{h}$ (the first option)
