What is the area of a triangle with base 10 cm and height 6 cm?
A
25 cm²
B
30 cm²
C
35 cm²
D
40 cm²
Correct Answer: Option B — 30 cm²
Explanation:
Area of triangle = (1/2) × base × height = (1/2) × 10 × 6 = 30 cm². This formula applies to all triangles when the perpendicular height is k...
Area of triangle = (1/2) × base × height = (1/2) × 10 × 6 = 30 cm². This formula applies to all triangles when the perpendicular height is known. For triangles where only sides are given Heron's formula is used. Triangle area calculations are fundamental and appear across all competitive exam geometry sections.
