Explanation
the area of a rectangle is given by:
[tex]A_{rec\tan gle}=length\cdot width[/tex]Step 1
Set the new measures
[tex]\begin{gathered} \text{length}_{new}=6+2=8\text{ ft} \\ \text{width}_{new}=4.5+1.5=6\text{ ft} \end{gathered}[/tex]Step 2
replace in the formula to find the new area
[tex]\begin{gathered} A_{rec\tan gle}=length\cdot width \\ A_{rec\tan gle}=8\text{ ft}\cdot\text{ 6 ft} \\ A_{rec\tan gle}=48\text{ sq ft} \\ \end{gathered}[/tex]so,the answer is
[tex]B)48\text{ sq ft}[/tex]I hope this helps you
