Answer key · Calculate the area of triangles using a formula

  1. 1.
    18 — Area = base × height ÷ 2 = 6 × 6 ÷ 2 = 18.
  2. 2.
    14 — Area = base × height ÷ 2 = 4 × 7 ÷ 2 = 14.
  3. 3.
    27 — Area = base × height ÷ 2 = 6 × 9 ÷ 2 = 27.
  4. 4.
    44 — Area = base × height ÷ 2 = 11 × 8 ÷ 2 = 44.
  5. 5.
    30 — Area = base × height ÷ 2 = 10 × 6 ÷ 2 = 30.
  6. 6.
    72 — Area = base × height ÷ 2 = 16 × 9 ÷ 2 = 72.
  7. 7.
    231 — Area = base × height ÷ 2 = 21 × 22 ÷ 2 = 231.
  8. 8.
    362.5 — Area = base × height ÷ 2 = 29 × 25 ÷ 2 = 362.5.
  9. 9.
    338 — Area = base × height ÷ 2 = 26 × 26 ÷ 2 = 338.
