Answer 2

$\bf\underline{\underline{\blue{SOLUTION:-}}}$

Question

• The side of a triangle are 122 m, 22m and 120m respectively. The area of the triangle is?

Answer

• Area = 1320m²

Given

• Side of Triangle = 122m , 22m , 120m

To Calculate

• Area of triangle __?

Step by Step Explanation

• Sides are 122m , 22m , 120m

Let

a= 122m

b= 22m

c= 120m

Semi perimeter = a+b+c /2

☞ 122 + 22 + 120 /2

☞ 264 /2

Semi perimeter ☞ 132m

☆ Using Heron's formula ☆

√s(s-a)(s-b)(s-c)

putting values,

☞ √132(132-122)(132-22)(132-120)

☞ √132( 10)(110)(12)

☞ √1742400

☞ 1320m²

$\bf\underline{\underline{\blue{HENCE:-}}}$

• Area of triangle = 1320m²
