The answer is 6.5 and what I did is I took the mixed fraction (2 2/4) and I turned It into a decimal. After I knew it was 2.5 all I had to do was use the formula A=lw to get my answer on what the width was.
Step 1: Replace the variables with numbers
A=lw A=2(1.25) A= 2.5 (Fraction 2 2/4)
Step 2: Use the perimeter formula (P=l+w+l+w or P=(l+w)2)
