For #7-9, find the area of each figure, round your answer to one decimal place if necessary.

Answer 1

7) 468 ft²

8) 864 m²

9) 192 cm²

Explanation:

To calculate the area of each given composite figure, divide the figure into two rectangles and sum the area of the two rectangles.

`\boxed{\begin{minipage}{5cm}\underline{Area of a rectangle}\\\\$A=w\cdot l$\\\\where:\\ \phantom{ww} $\bullet$ \quad $w$ is the width.\\ \phantom{ww} $\bullet$ \quad $l$ is the length.\\\end{minipage}}`

Question 7

Separate the figure into two rectangles by drawing a vertical line (see attachment).

`\begin{aligned}\textsf{Total Area}&=\textsf{Area 1}+\textsf{Area 2}\\&=16 \cdot 17 + 14 \cdot 14\\&=272+196\\&=468\; \sf ft^2\end{aligned}`

Question 8

Separate the figure into two rectangles by drawing a horizontal line (see attachment).

`\begin{aligned}\textsf{Total Area}&=\textsf{Area 1}+\textsf{Area 2}\\&=18 \cdot 18 + 30 \cdot 18\\&=324+540\\&=864\; \sf m^2\end{aligned}`

Question 9

Separate the figure into two rectangles by drawing a horizontal line (see attachment).

`\begin{aligned}\textsf{Total Area}&=\textsf{Area 1}+\textsf{Area 2}\\&=8 \cdot 8+16 \cdot 8\\&=64+128\\&=192\; \sf cm^2\end{aligned}`
