the perimeter is equal to the sum of all the sides, therefore:
[tex]\begin{gathered} P=w+w+l+l=48 \\ so\colon \\ w=12 \\ l=12 \\ P=12+12+12+12=48 \end{gathered}[/tex]
----------------------------------------
The area of a rectangle is given by:
[tex]\begin{gathered} A=w\cdot l \\ where \\ l=24 \\ w=17 \\ A=24\cdot17 \\ A=408in^2 \end{gathered}[/tex]
