Answer:
157.78
Explanation:
Solve each shape individually
For the square, we are given both side lengths so multiply them to find its area
9.8 x 8.7 = 85.26m
For the triangle on the right, we know the base and height lengths, so multiply them and divide by two to find the area
9.8 x 7.2 = 70.56 / 2 = 35.28m
For the triangle on the left, we can find the base by subtracting the side length of the square from the length given on the bottom
16.3 - 8.7 = 7.6
We know the height for this triangle so multiply that by the number you just found and divide by two to find the area
9.8 x 7.6 = 74.48 / 2 = 37.24m
Finally add all of the areas found together to get the total area of the trapezoid
37.24 + 35.28 + 85.26 = 157.78
