The area of a triangle is given by the formula A = 1/2 * base * height.
Given that the base of the triangle is 7 inches and the area is 43.75 square inches, we can plug these values into the formula:
43.75 = 1/2 * 7 * height
Solving for height:
43.75 = 3.5 * height
height = 43.75 / 3.5
height = 12.5 inches
Therefore, the height of Rainee's triangle is 12.5 inches.
