Answer:

90

Step-by-step explanation:

First, let's make a line of separation to make a rectangle and triangle.

Now, we know the area of a rectangle is l × w, where l = length and w = width. The length and width of this rectangle is is 8 and 9, so 8 × 9 = 72.

Next, the area of a triangle is bh ÷ 2, where b = base and h = height. We're given the base of the triangle as 9 m. To find the height, we subtract 8 from 12 and get 4. 9 multiplied by 4 is 36, and 36 divided by 2 is 18.

Lastly, we combine the area of the rectangle and triangle. 72 + 18 = 90.

Therefore, the answer is 90 m^2.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
