Question

if the sides of a triangle are 6 meters, 7 meters and 8 meters then area of a triangle is..... ​

Answer 1

HEY_DEAR______❤❤❤❤❤

#=>FIRST CHECK OUT THE QUESTION...TRIANGLE WILL NOT BE FORMED ACCORDING TO THE GIVEN SIDES........

#IN CASE IF IT IS FORMED THEN...

=>AREA OF TRIANGLE = BY HERON'S FORMULA...

Answer 2

$\huge\bold\pink{SOLUTION:-}$

a= 6m

b= 7m

c= 8m

$s = \frac{a + b + c}{2}$

$→s = \frac{6 + 7 + 8}{2}$

$→s = \frac{21}{2}$

By, applying , Heron's formula, we get:-

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

$→ \sqrt{ \frac{21}{2} ( \frac{21}{2 } - 6)( \frac{21}{2} - 7)( \frac{ 21}{2 - 8} )}$

$→ \sqrt{ \frac{21}{2 } ( \frac{21 - 12}{2} )( \frac{21 - 14}{2} )( \frac{21 - 16}{2} )}$

$→ \sqrt{ \frac{21}{2} ( \frac{9}{2} )( \frac{7}{2} )( \frac{5}{2} )}$

$→ \sqrt{ \frac{6615}{2} }$

Therefore,

The area of the ∆ is 3307.5
