Question

what is the area of this figure? 3 km 3 km 6 km 9 km 6 km 9 km square kilometers submit

Explanation:

Step1: Divide figure into rectangles

We can divide the given figure into two rectangles. One rectangle has dimensions 3 km by 9 km and the other has dimensions 6 km by 6 km.

Step2: Calculate area of first rectangle

The area formula for a rectangle is $A = l\times w$. For the first rectangle with length $l = 9$ km and width $w = 3$ km, the area $A_1=9\times3 = 27$ km².

Step3: Calculate area of second rectangle

For the second rectangle with length $l = 6$ km and width $w = 6$ km, the area $A_2=6\times6=36$ km².

Step4: Calculate total area

The total area $A$ of the figure is the sum of the areas of the two rectangles, so $A = A_1+A_2=27 + 36=63$ km².

Answer:

63
