Find the area of the triangle whose sides are 13 cm, 14 cm and 15 cm
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e 84 cm2.
The sides of the triangle
a = 13 cm, b = 14 cm and c = 15 cm
By using Heron's Formula
Area of Triangle = √s(s-a)(s-b)(s-c)
s = (a + b + c)/2
= (13 + 14 + 15)/2
= 42/2 = 21
Area =
=
= 84 cm2
