The area of a triangle is 250 cm2 . The ratio of its base to its height is 5 : 4. Find the length of its base.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 25 cm
Let base = 5x and height = 4x.
Area = 1/2 × base × height
⇒ 250 = 1/2 × 5x × 4x
⇒ 250 = 10x2
⇒ x2 = 25
⇒ x = 5
Base = 5x = 25 cm
