Answer:

4 ft = height

10 ft = base

Explanation:

The area of a triangle is given by ...

A = 1/2bh

Filling in the given value, we get the relation ...

20 = 1/2bh

40 = bh

We know the factors of 40 are ...

40 = 1×40 = 2×20 = 4×10 = 5×8

Of the numbers that area available, only the pair 4×10 will give the desired result.

The height is 4 ft; the base is 10 ft.
