$2918.625\ ft^2$
To find the square footage, first convert the dimensions to feet. $45\ ft+3\ in=45\ ft+(3\ in\times\frac{1\ ft}{12\ in})=45\ ft+\frac{3}{12}\ ft=45\ ft+\frac{1}{4}\ ft=45.25\ ft$ $64\ ft+6\ in=64\ ft+(6\ in\times\frac{1\ ft}{12\ in})=64\ ft+\frac{6}{12}\ ft=64\ ft+\frac{1}{2}\ ft=64.5\ ft$ Multiply to find the square footage, which is the same as finding the area. $45.25\times64.5=2918.625\ ft^2$
