12b=Ah
1 half b is equal to cap A over h

b=A2h
b is equal to cap A over 2 h

b=2Ah
b is equal to 2 cap A over h

b=2(A−h)

Answer 1

To solve the area formula \( A = \frac{1}{2}hb \) for \( b \), we need to isolate \( b \) on one side of the equation.

Starting with the formula:

\[ A = \frac{1}{2}hb \]

We can multiply both sides by 2 to eliminate the fraction:

\[ 2A = hb \]

Next, we divide both sides by \( h \) to solve for \( b \):

\[ b = \frac{2A}{h} \]

So the correct response is:

b is equal to \( \frac{2A}{h} \).
