Answer:
The area of the rectangle is 40 and the area is the triangle is 20 therefore, the area of the shape is 60
Explanation:
Rectangle:
8cm x 5cm = 40cm
Triangle (1/2bxh)
The base of the triangle would be 8 cm as the top and the bottom of the rectangle is the same width. The height was given to be 5 cm (note the height is the dotted line) Therefore the area of the triangle is half the base which is (8×1/2 = 4) times the height (5); which is 20.
