Question

Use the ruler provided on the parallelogram below to measure its dimensions to the nearest Inch. 2. Which measurement is closest to the area of the parallelogram in square Inches? A 8 in.? B 31 in? C6 in. D7in?

Answer 1

Notice that the height of the parallelogram measures 2 inches, while the base measures 3.25 = 3 1/4 inches. Then, the area of the parallelogram is:

$\begin{gathered} A=2\cdot3\frac{1}{4}=2\cdot\frac{13}{4}=\frac{2\cdot13}{4}=\frac{26}{4}=\frac{13}{2}=6\frac{1}{2} \\ \Rightarrow A=6\frac{1}{2}in^2 \end{gathered}$

thus, the area is 6 1/2 in^2
