Question

9/10/25 exit ticket - solving equations
the formula for the area of a triangle is $a = \frac{1}{2}bh$. solve the equation for b.
$\frac{a}{2h}=b$
$\frac{2a}{h}=b$
$b = a - \frac{1}{2}h$
$\frac{2a}{b}=h$

Explanation:

Step1: Multiply both sides by 2

$2A = bh$

Step2: Divide both sides by h

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

Answer:

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