Question #N414
The area of a triangle is 42 square units. If the base of the triangle has a length of 14 units, what is the length of the altitude to that base?
A. 3
B. 6
C. 12
D. 21
Correct Answer is: B
The area of a triangle is given by the formula (1/2)bh, where b is the length of the base and h is the length of the altitude. We know the area is 42 square units and the base is 14 units. Substituting these values into the formula, we get 42 = (1/2)(14)h. Simplifying, we get 42 = 7h. Dividing both sides by 7, we get h = 6. Therefore, the length of the altitude is 6 units.
