A triangle with area 100 m² has height double its base. What are its dimensions?
Show answer & explanation
Correct answer: A
Explanation
Area = 100, Height = 2 × Base
Area of the triangle = (1/2) × Base × Height
100 = (1/2) × b × (2b)
100 = b²
b = 10
Height = 2b = 20
Base = 10 meters, Height = 20 meters
