If the area of a triangle whose base measures 6 cm is 18 cm2, then its height is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 6 cm.
We know the formula for the area of a triangle is:
Area = (1/2) × base × height
We are given:
Area = 18 cm²
Base = 6 cm
18 = (1/2) × 6 × height
⇒ 18 = 3 × height
⇒ height = 6 cm
So, the height of the triangle is 6 cm.
