Chapter 12.1, Problem 33SR

To determine

The area of each figure.

Answer to Problem 33SR

The area of the figure is $72ft.$

Explanation of Solution

Given:

Concept Used:

Rectangal Area:

  $A=l\times w$

Where,

  $l:$ Length

  $w:$ Width

Here, 2 rectangulars are available so, first calculate the area of rectangle 1.

  $\begin{array}{l}A=l\times w\\ A=10\times 4\\ A=40ft.\end{array}$

Now, calculate the area of rectangle 2.

  $\begin{array}{l}A=l\times w\\ A=4\times 8\\ A=32ft.\end{array}$

Total area of these 2 rectnagle is,

  $40ft.+32ft=72ft.$

Conclusion:

Hence, the area of the figure is $72ft.$
