Question

this figure is made of three squares joined together. what is the area of the figure in square inches? a. 9 square inches b. 18 square inches c. 27 square inches d. 81 square inches

Explanation:

Step1: Find area of one square

The area formula for a square is $A = s^2$, where $s$ is the side - length. Given $s = 3$ inches, then $A_1=3^2=9$ square inches.

Step2: Calculate total area

The figure is made up of 3 squares. So the total area $A = 3\times A_1$. Substitute $A_1 = 9$ square inches into the formula, we get $A=3\times9 = 27$ square inches.

Answer:

C. 27 square inches
