Question

guided practice: rearrange formulas the formula for the area of a triangle is a = 1/2(bh), where b is the base and h is the height. use the drop - down arrows to complete the sentences about how to solve for the base, b. to solve for the base, b, of the triangle, first next, to isolate the base, b, then, the rearranged formula for the base, b, is

Explanation:

Step1: Eliminate the fraction

Multiply both sides of $A = \frac{1}{2}(bh)$ by 2 to get $2A=bh$.

Step2: Isolate the variable b

Divide both sides of $2A = bh$ by h, so $b=\frac{2A}{h}$.

Answer:

1. Multiply both sides by 2.
2. Divide both sides by h.
3. $b=\frac{2A}{h}$
