Answer:
379m^2
Explanation:
We need to approach this problem by first sectioning this figure out. The top left corner is a square, 5x5. The top right is 6x5, and the rest is a rectangle. This rectangle has the dimensions 23-5 by 18. After multiplying 5x5 we get 25, 6x5 is 30, and 18 x 18 is 324. We add this all together to get 379.
