Alexandra made a rectangular quilt the measured 3 1/4. 2 3/4 feet in width. What is the area of the quilt in square feet? Write an equation to solve.

Correct answer:

A =  8.9375 ft²

Step-by-step explanation:

$$\begin{gathered} a=3{\displaystyle \frac{1}{4}}=3+{\displaystyle \frac{1}{4}}={\displaystyle \frac{3\cdot 4+1}{4}}={\displaystyle \frac{13}{4}}=3.25\text{ ft } \\ b=2{\displaystyle \frac{3}{4}}=2+{\displaystyle \frac{3}{4}}={\displaystyle \frac{2\cdot 4+3}{4}}={\displaystyle \frac{11}{4}}=2.75\text{ ft } \\ A=a\cdot b=3.25\cdot 2.75={\displaystyle \frac{143}{16}}{\text{ft}}^2=8\frac{15}{16}{\text{ft}}^2=8.9375{\text{ft}}^2 \end{gathered}$$
