Answer:
Area = 174m²
Explanation:
To find the area of the composite figure above, we have to break it into simpler or easy figures to solve.
In the figure above, we have a right angle triangle sitting above a rectangle
1.
To find the area of the triangle, we use the formula
A = ½b * h
Where b = breadth
h = height
Height of the triangle = 12m
Breadth of the triangle = 5m
Area = ½ * 5 * 12
Area = ½ * 60
Area = 30m²
2.
Area of the rectangle = L * W
L = length of the rectangle
W = width of the rectangle
Area = 12 * 12
Area = 144m²
Area of the composite figure = area of the triangle + area of rectangle
Area = 30 + 144
Area = 174m²
