The area of the triangle below is 2/5 square foot. What is the length, in feet, of the base of the triangle? Area = bh/2

2/3 feet.

Step-by-step explanation:

We have to calculate the length of the base of the triangle, in this case they give us the area of the triangle but still it is necessary to know the height of the triangle to calculate the length of the base, otherwise it would be impossible.

I have found an image where the graph is, which I will attach where you can see that the height is 6/5 ft. The area of the triangle is:

A = b * h / 2

solved for b which is the length of the base of the triangle would be:

b = 2 * A / h

replacing:

b = 2 * (2/5) / (6/5)

b = 20/30

b = 2/3

Which means that the length of the base of that triangle is 2/3 feet.
