Answer: #1 108 #2 526. #3 512

Explanation:

6*6=36 +12*6 = 108

22*3=66 + 20*23= 460 460+66=526

16*16=256 + 32*8=256 256+256=512

Answer:

1) 108 cm²

2) 906 ft²

3) 512 m²

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 1

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


\begin{aligned}\textsf{Total Area}&=\textsf{Area 1}+\textsf{Area 2}\\&= 6\cdot 6+12 \cdot 6\\&=36+72\\&=108\; \sf cm^2\end{aligned}

Question 2

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


\begin{aligned}\textsf{Total Area}&=\textsf{Area 1}+\textsf{Area 2}\\&= 22\cdot23 + 20\cdot 20\\&=506+400\\&=906\; \sf ft^2\end{aligned}

Question 3

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


\begin{aligned}\textsf{Total Area}&=\textsf{Area 1}+\textsf{Area 2}\\&= 16\cdot16 + 32\cdot 8\\&=256+256\\&=512\; \sf m^2\end{aligned}
