Jamie measures the length and height of a triangular flag. If the flag's base is 3 feet and the area is 9 feet squared, what is the height of the flag?

A. 3 feet
B. 27 feet
C. 6 feet
D. 8 feet

C. 6 feet

The formula for the area of a triangle is 1/2 * base * height.
Given that the base is 3 feet and the area is 9 feet squared, we can plug in the values to find the height:
9 = 1/2 * 3 * height
9 = 1.5 * height
height = 9 / 1.5 = 6

Therefore, the height of the flag is 6 feet.
