Answer 2

Answer: $150ft^2$

Step-by-step explanation:

length: $7\frac{1}{2}in$ Convert to an improper fraction. $\frac{7*2+1}{2}=\frac{15}{2}$

width: $5 in$

$Formula: A=w*l$

$A=(5in)(\frac{15}{2}in)\\A=\frac{75}{2}in^2$

Convert to ft. I assume your conversion factor is $\frac{1}{2}in. : 1ft$. However, the unit we need is squared. Square both sides.

$(\frac{1}{2}in.)^2 : (1ft)^2$

$\frac{1}{4}in^2 : 1ft^2$

Convert.

$\frac{75}{2}in^2(\frac{1ft^2}{\frac{1}{4}in^2 } )=$

Invert the fraction in the denominator and multiply it by the numerator.

$\frac{75}{2}in^2*1ft^2*4in^-^2=75*2ft^2=150ft^2$
