Question

the formula for the area of a triangle is ( a = \frac{bh}{2} ). solve for b.

Explanation:

Step1: Multiply both sides by 2

To isolate the term with \( b \), we multiply both sides of the equation \( A = \frac{bh}{2} \) by 2. This gives us \( 2A = bh \).

Step2: Divide both sides by \( h \)

Now, to solve for \( b \), we divide both sides of the equation \( 2A = bh \) by \( h \) (assuming \( h
eq 0 \)). This results in \( b=\frac{2A}{h} \).

Answer:

\( b = \frac{2A}{h} \)
