If the sides of a triangle
the triangle.​

Answer 1

Correct Question:-

If the sides of a triangle are 8m, 9m and 13 m. find the area of the triangle.

Given:-

8m , 9m , 13m.

To find:-

The Area.

Step By Step Explanation:-

Area of A Triangle = Side × Side × Side

= 8 × 9 × 13

= 936m

Solution:-

The Area of Triangle is 936m. Whose Sides are 8m , 9m , 13m.

$\mathsf {\fbox{Answer~is~936m}}$

Answer 2

Answer:

area of triangle is 35.49

$m {}^{2}$

Step-by-step explanation:

use heron's formula to find area of triangle

$\sqrt{s(s - a)(s - b)(s - c) }$

where, a,b,c are sides of a triangle and a is the average of sides of triangle

in this question,

s =

$(a + b + c) \2$

= (8+9+13)/2

= 15

Putting all values in the formula,

A =

$\sqrt{15(15 - 8)(15 - 9)(15 - 13)}$

$\sqrt{15 \times 7 \times 6 \times 2}$

=

$\sqrt{1260}$

= 35.49
