A triangular flag has base and height in the ratio 5 : 4. If the area is 160 cm2, what are the base and height?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 20 cm and 16 cm.
Let base = 5x cm and Height = 4x cm
Area = (1/2) × Base × Height = (1/2) × 5x × 4x = 10x2 cm2
10x2 = 160
⇒ x2 = 16
⇒ x = 4
Base = 5 × 4 = 20 cm, Height = 4 × 4 = 16 cm
