# SHORTCUT METHOD TO FIND AREA OF TRIANGLE IF ITS THREE SIDES ARE GIVEN

147 Points
11 years ago

Dear Aman Singh

If the side is given

then check if square of any side is equal to the sum of square of other two side .c2=a2+b2

then triangle is right angel triangle

area can be calculate by  1/2 a* b

if all the side are equal then area =√3/4 *a2

other wise you can use the formula

area=√s(s-a)(s-b)(s-c)

where a,b,c are side of triangel  and s=(a+b+c)/2
