Question

Solve A=1/2bh for b when A = 126 and h =18.

Answer 1

b=14

Step-by-step explanation:

Given the equation:

`A=(1)/(2)bh`

When A=126 and h=18. we have that:

`126=(1)/(2)* b*18`

We then solve for b.

`\begin{gathered} 126=(1)/(2)*18* b \\ 126=9b \\ \text{Divide both sides by 9} \\ (126)/(9)=(9b)/(9) \\ b=14 \end{gathered}`

The value of b is 14.
