Answer:
The height of the pennant is 3 feet.
Explanation:
The pennant has a triangular shape, therefore the area of the pennant is given by the following formula:
area = (1/2)*b*h
Since we were given the value for the area, which is 2.25 square feet, and the value for the base, which is 1.5 feet, we can solve for the height of the triangle. Applying this data for the formula:
2.25 = (1/2)*1.5*h
2.25 = 0.75*h
0.75*h = 2.25
h =2.25 / 0.75
h = 3 feet
The height of the pennant is 3 feet.
