Formula for Area of a rectangle :


\boxed {\boxed {\text {Area of a rectangle = Length x Width}}}


\text {Given that the area is }8 (3)/(4)\ \ ft^2 \text { and the length is } 3 (1)/(2) \ ft,


8 (3)/(4) = 3 (1)/(2) * \text{ width}

Find width:

\text{ width} = 8 (3)/(4) / 3 (1)/(2)

Change to improper fraction:

\text{ width} = (35)/(4) / (7)/(2)

Change divide fraction to multiplication fraction:

\text{ width} = (35)/(4) * (2)/(7)

Multiply them:

\text{ width} = (5)/(2)

Simplify to mixed number:

\text{ width} = 2(1)/(2) \text{ ft}


\boxed {\boxed {\text {Answer : Width = } 2(1)/(2) \text {ft. } }}
