Step-by-step explanation:
This is a quadratic formula meaning that you must take the a value (1) b value (3) and the c value (108) and plug it into the quadratic formula.
which simplifies to -3 add or subtract the sqrt of 441 divided by two.
We will have to use the formula for the area of a trapezoid on this problem, which is ( and
are the bases of the trapezoid and
is the height):
All we need to do is substitute the information we are given into our formula:
Now, let's just simplify the equation:
The missing base has a length of 13 units.
