ivolga24 [154]

Answer:

The area of the piece of construction paper is $\frac{261}{4} inches^2$

Step-by-step explanation:

Length of construction paper = $6 \frac{3}{4} inches$

= $\frac{27}{4} inches$

Width of construction paper = $9 \frac{2}{3} inches$

= $\frac{29}{3} inches$

Area of construction paper = $Length \times Width$

Area of construction paper = $\frac{27}{4} \times \frac{29}{3}$

= $\frac{261}{4} inches^2$

Hence the area of the piece of construction paper is $\frac{261}{4} inches^2$
