For this case we have that by definition, the area of a triangle is given by:

Where:
b: It is the base of the triangle
h: It is the height of the triangle
According to the statement data we have:

Substituting we have:

We divide between 2 on both sides:

We factor by looking for two numbers that, when multiplied, are obtained -88 and when added together, +3 is obtained.
These numbers are +11 and -8.

We have two roots:

We choose the positive value.
Thus, the base of the triangle is:
Answer:
The base of the triangle is 22 units.
