Question

use formulas to find the area of the figure. 18 ft 4 ft 14 ft 4 ft a. 94 ft² b. 92 ft² c. 128 ft² d. 86 ft²

Explanation:

Step1: Divide the figure into rectangles

The figure can be divided into two rectangles. One rectangle has dimensions 18 ft by 4 ft and the other has dimensions 4 ft by 14 ft.

Step2: Calculate area of first rectangle

The area formula for a rectangle is $A = l\times w$. For the first rectangle with length $l = 18$ ft and width $w = 4$ ft, $A_1=18\times4 = 72$ ft².

Step3: Calculate area of second rectangle

For the second rectangle with length $l = 14$ ft and width $w = 4$ ft, $A_2=14\times4=56$ ft².

Step4: Calculate total area

The total area $A = A_1+A_2$. So $A=72 + 56=128$ ft².

Answer:

C. 128 ft²
