A triangle has an area of 15 square feet. the height is 8 feet.What is the length of the base?

1/2 b*h=15

b*8=30
b= 30/8

3.75

i don't know but the answer is 3.75

To find the length of the base of a triangle when given the area and the height, you can use the formula for the area of a triangle:

Area = (1/2) * base * height

In this case, you know that the area is 15 square feet and the height is 8 feet.

15 = (1/2) * base * 8

To solve for the base, you can rearrange the equation:

15 = 4 * base

Divide both sides of the equation by 4:

15/4 = base

So, the base of the triangle is 15/4 feet, or 3.75 feet.
