The lengths of the three sides of a triangle are 3 cm, 4 cm and 5 cm respectively. Find the area of this triangle.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 6 cm2
Given:
Sides of triangle are 3, 4 and 5.
Formula used:
Area of triangle = (1/2) × base × height ---- (1)
Calculations:
The given sides of the triangle follow Pythagoras theorem;
Height = 4 cm, base = 3 cm and Hypotenuse = 5 cm
Area of triangle = (1/2) × 3 × 4 = 6 cm2
