Hello, I really can not understand the solution
The question is find area of a right angle triangle with side -5, 12, 13 cm
Answer provided by our tutors
To find the area you need to use Heron's formula:
So, in your case:
a = 5 cm
b = 12 cm
c = 13 cm
s = (5 + 12 + 13)/2
s = 15
Now, lets plug in the values in the formula for area and use the solver to calculate.
