Answer:
It's 16m
Step-by-step explanation:
Let's say the missing side is C, and since the triangle is right-angle triangle, you can use Pythagoras theorem. Which is
C squared is equal to A squared plus B squared
Like this: c^2 = a^2+b^2
Then
c^2= (10)^2 + (12)^2
c^2= 100 + 144
c^2= 244
c=

c = 15.6

Answer:
34.65
Step-by-step explanation:
Compare the values they have given you with the diagram. a, b and c are all sides of the triangle they want you to find the perimeter of. Knowing this, all you have to do is add a, b and c. h is not important because you don't count the altitude of a triangle when you calculate perimeter.
12 + 10 + 12 = 34
The perimeter of the triangle is 34 ft.
