Question

Using Herons formula
, Find the
area of the triangle whose
sides are 22 cm, 12 cm and 122 cm.​

Answer 1

Answer:

Step-by-step explanation:

• Area of the triangle is 1320cm².

Given :-

• Sides of a triangle as 22cm, 120cm and 122cm.

To Find :-

• Area of the triangle.

SoluTion :-

Here,

• a = 22

• b = 120

• c = 122

★ S = a + b + c /2

→ S = 22 + 120 + 122 / 2

→ S = 264 / 2

→ S = 132

By heron's formula

Area of ∆ :-

Hence, the area of the traingle is 1320cm².
