Question

charlie runs a screen printing company and is resetting a machine he uses to print triangular banners. he knows of material he needs for the banner as well as the height of the triangle, but he needs to set the machine to a new measurement for the triangles base. to help charlie determine the new measurement, rewrite the standard formula for the area of a triangle, $a=\frac{1}{2}bh$ for the base, $b$. enter the correct answer in the box. $b =$

Explanation:

Step1: Start with area formula

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

Step2: Isolate the base $b$

Multiply both sides by 2 to get $2A = bh$. Then divide both sides by $h$: $b=\frac{2A}{h}$

Answer:

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