Answer:
87.8 square meters
Step-by-step explanation:
First of all, find the area of the three recthangles.They are all 9m long and 3m wide. 9*3 is 27, and since there are three of them, 27*3 is 81.
To find the area of the two triangles, you could do 3*2.6. Normally, you would halve the values because they are triangles but since there's two of them it cancels out.
3*2.6 is 7.8, and adding that to the area of the rectangles gets the equation 81+7.8 which comes out to 87.8 square meters.
What are we doing, adding, subtracting, multiplying.....
