Question

Keith made a rectangular sign that had a perimeter of 48 inches. Which model could represent the sign Keith made

Answer 1

the perimeter is equal to the sum of all the sides, therefore:

$\begin{gathered} P=w+w+l+l=48 \\ so\colon \\ w=12 \\ l=12 \\ P=12+12+12+12=48 \end{gathered}$

----------------------------------------

The area of a rectangle is given by:

$\begin{gathered} A=w\cdot l \\ where \\ l=24 \\ w=17 \\ A=24\cdot17 \\ A=408in^2 \end{gathered}$
