Answer: Length = 8 inches
Step-by-step explanation:
To find the length of the base of the triangle, we can use the formula for the area of a triangle:
Area = 1/2 x base x height
Given that the area is 30 square inches and the height is 7.5 inches, we can plug these values into the formula and solve for the base:
30 = 1/2 x base x 7.5
2 x 30 = base x 7.5
60 = base x 7.5
base = 60/7.5
base = 8
So, the length of the base of the triangle is 8 inches.
