The area of a trieangle is 16 ft. squared. The lenght of one side is 8ft. How long is the base?

More information is required. Is the triangle isosceles? Or a right triangle?

Given one side length and the area, there are an infinite number of possibilities for the two other side lengths.

To find the length of the base of the triangle, we can use the formula for the area of a triangle.

The area of a triangle is given as:
Area = (1/2) * base * height

In this case, we know that the area is 16 ft² and the height (or the length of one side) is 8 ft. Let's substitute these values into the formula:

16 = (1/2) * base * 8

To isolate the base, we can rearrange the equation:

16 = 4 * base

Dividing both sides of the equation by 4:

4 = base

Therefore, the length of the base is 4 ft.
