Answer 1

120

The area of a rectangle is width times height.
In this example, width = Q1 (40)- 0 = 40 and height = P1 3 - 0 = 3

Therefore, the area = 40 times 3 = 120.

Answer 2

300

The area of a triangle is (1/2) times base times height.
In this example, base = Q1 (30) - 0 = 30 and height = P2 (28) - P1 (8) = 28 - 8 = 20

Therefore, the area = (1/2) times 30 times 20 = 300
