Question

what is the area of this figure? square miles

Explanation:

Step1: Divide the figure into rectangles

We can divide the figure into two rectangles. One rectangle with length 9 mi and width 3 mi, and another with length 4 mi and width 4 mi.

Step2: Calculate area of first rectangle

The area formula for a rectangle is $A = l\times w$. For the first rectangle with $l = 9$ mi and $w = 3$ mi, $A_1=9\times3 = 27$ square - miles.

Step3: Calculate area of second rectangle

For the second rectangle with $l = 4$ mi and $w = 4$ mi, $A_2 = 4\times4=16$ square - miles.

Step4: Calculate total area

The total area of the figure $A = A_1+A_2$. So $A=27 + 16=43$ square - miles.

Answer:

43
