If the area A of a triangle is 45 m2 (square meters) and the altitude h is 15 m, what's the base b?
2 answers:
Answer:
The base b is 6m
Step-by-step explanation:
The area A of a triangle with base b and height h is given by the formula;
The area of the triangle is given as 45 while the height h is 15. We substitute these known values into the formula above and solve for the unknown base;
We finally divide both sides by 15 to solve for b;
b = 90/15 = 6
Therefore, the base of the triangle is 6 m
Answer:
Step-by-step explanation:
The area of a triangle is
Where b is the base of the triangle and ha is the height.
In this case we have a triangle with area
and with height:
So the base of the triangle is:
Finally the base of the triangle is b = 6 meters
