Answer:
130^2 or 130 meters squared
Step-by-step explanation:
I decomposed the figure, then found the area of the decomposed figures then found the sum of them.
FIGURE A:
3 x 3 = 9
= 9^2
FIGURE B:
11 x 11 = 121
= 121 meters^2
So 121 + 9 = 130
= 130 meters^2
REMEMBER!!!!
THE FORMULA FOR AREA IS LENGTH * WIDTH = AREA
