The lengths of the three sides of a triangle are 3 cm, 4 cm and 5 cm respectively. Find the area of this triangle.
Answer & explanation
Correct answer: option 1
The sides of the triangle is given = 3, 4, and 5.
So we can say that this is a right angle triangle because 3,4 and 5 is a triplet.
So, Area of right angled triangle = \(\frac{1}{2}\) × Base × Height
= \(\frac{1}{2}\) × 4× 3 = 6cm2
