Try a sample
A triangle has base 4 cm and perpendicular height 11 cm. What is its area in square centimeters?
- 24
- 22
- 25
- 21
See the answer & why
22
Area = ½ × base × perpendicular height = ½ × 4 × 11 = 22.
A little hint: A triangle covers half of a rectangle with the same base and height.
A teaching tip
Check that the height is perpendicular to the chosen base.
