Question

The area of a triangle can be calculated from Heron's formula.
A= square s(s-a)(s-b)(s-c),
where a,b,and c are the side lengths and s= a+b+c divide by 2. Calculate the area of a triangle with side lengths 5,7, and 10. Leave your answer in simplest radical form.

Answer 1

first,find out semi-perimeter of triangle

Answer 2

\[\large \bf s=\frac{a+b+c}{2}=\frac{5+7+10}{2}=11\]

Answer 3

ok

Answer 4

now,use HERON'S FORMULA :-
\[\huge \bf \sqrt{s(s-a)(s-b)(s-c)}\]
\[\large \bf \sqrt{11(11-5)(11-7)(11-10)}\]

Answer 5

Then what

Answer 6

find out the value !!

Answer 7

i mean simplify it and get your answer :)

Answer 8

ok

Answer 9

so what is the answer ???

Answer 10

wait a second

Answer 11

give me some time

Answer 12

okk

Answer 13

So it be like 2 sqaure 66

Answer 14

correct !!!
\[\large \bf 2\sqrt{66}=16.24=\color{red}{Answer}\]

Answer 15
