The area for a rectangle is given by the next formula:
[tex]A_r=Length\cdot Width[/tex]Now, the values of the rectangle are given in the mixed form.
Then, we can convert these values from mixed numbers to fractions:
[tex]5\frac{3}{8}ft=5ft+\frac{3}{8}ft=\frac{43}{8}ft[/tex]and
[tex]3\frac{1}{4}ft=3ft+\frac{1}{4}ft=\frac{13}{4}ft[/tex]Now, we can use the area formula:
[tex]A_r=\frac{43}{8}ft\cdot\frac{13}{4}ft[/tex]Then
[tex]A_r=\frac{559}{32}ft^2[/tex]
