Question

how to measure the area of a triangle

Answer 1

U can use the below

1/2breadth *height




√3\4a^2(for equilateral triangle only)




√s(s-a))(s-b) (s-c) where s =a+b+c\2
A b c are sides of triangle

Answer 2

hello friend!

To find out the area of the triangle u can use 
A= 1/2 x l x b x h 
 
or 

if they are given with 3 values..
you can use Heron's formula

s= a + b+ c ( s=semiperimeter)
A = √s(s-a)(s-b)(s-c)

hope it helps!
