what is the area of this figure? 5 km 2 km 2 km 5 km 3 km 7 km square kilometers

Explanation:

Step1: Divide the figure into rectangles

We can divide the given figure into two rectangles. One rectangle with length 5 km and width 5 km, and another with length 2 km and width 3 km.

Step2: Calculate area of first rectangle

The area formula for a rectangle is $A = l\times w$. For the first rectangle with $l = 5$ km and $w = 5$ km, $A_1=5\times5 = 25$ km².

Step3: Calculate area of second rectangle

For the second rectangle with $l = 2$ km and $w = 3$ km, $A_2=2\times3=6$ km².

Step4: Calculate total area

The total area of the figure $A = A_1 + A_2$. So $A=25 + 6=31$ km².
