Question

find area of triangle 39m,52m,65m by herons formula​

Answer 1

Step-by-step explanation:

s= 39+52+65/2

s= 156/2

s= 78

area = √ s(s-a)(s-b)(s-c)

= √78(78-39)(78-52)(78-65)

=√78(39)(26)(13)

= √1028196

= 1014m²

Answer 2

Answer :-

• Area of Triangle = 1014 sq.m.

Explanation :-

Given : Sides of triangle are 39m, 52m and 65m.

To Find : Area of Triangle.

Solution :

First Let's Calculate Semi Perimeter.

Semi Perimeter = (a + b + c)/2.

Here,

• a = 39 m.
• b = 52 m.
• c = 65 m.

➞ S = (39 + 52 + 65)/2.

➞ S = (91 + 65)/2.

➞ S = 156/2.

➞ S = 78 m.

Now, Let's Calculate Area by Heron's Formula.

Formula Used :-

Area = √s(s - a)(s - b)(s - c).

➞ Area = √78(78 - 39)(78 - 52)(78 - 65).

➞ Area = √78(39)(26)(13).

➞ Area = √3042 × 338.

➞ Area = √1028196.

➞ Area = 1014 sq.m.

Therefore, Area of Triangle = 1014 sq.m.
