Question

The area of a rectangular picture frame is 93.5 square inches. The area formula for a rectangle is A = l.w .Write and solve an equation to find the width, w, of the picture frame. 11 in. W Equation: w Solution: W= in.

Answer 1

The area is given by:

$\begin{gathered} A=w\cdot l \\ \text{where:} \\ w=\text{width} \\ l=\text{length}=11in \\ A=93.5in^2 \end{gathered}$

Therefore:

$93.5=11w$

Solve for w:

$\begin{gathered} w=\frac{93.5}{11} \\ w=8.5in \end{gathered}$
