Answer:

a)  30 square units

b)  36 square units

c)  18 square units

Step-by-step explanation:

Area of a triangle = 1/2 × base × height

Part (a)

Base = 10

Height = 6

⇒ Area = 1/2 × base × height

            = 1/2 × 10 × 6

            = 30 units²

Part (b)

  • Base = 12
  • Height = 6

⇒ Area = 1/2 × base × height

            = 1/2 × 12 × 6

            = 36 units²

Part (c)

  • Base = 6
  • Height = 6

⇒ Area = 1/2 × base × height

            = 1/2 × 6 × 6

            = 18 units²
