Answer:
Total Area = 110 m²
Explanation:
To find the area of this composite shape, extend the top horizontal line to the right. That divides the figure into a right triangle (above the extended line) and a rectangle (below the extended line).
Shape 1
Name: triangle
Formula: A = 1/2bh
Values: b = 15 m -5 m = 10 m; h = 4 m
Area = 1/2(10 m)(4 m) = 20 m²
__
Shape 2
Name: rectangle
Formula: A = bh
Values: b = 15 m; h = 6 m
Area = (15 m)(6 m) = 90 m²
__
Total area = Shape 1 area + Shape 2 area
Total area = (20 m²) +(90 m²) = 110 m²
