Answer: the answer is 7
Step-by-step explanation:
Area of quadrilateral= Length x Width
a+5 times a-2 = 60 which is the area
7+5 times 7-2= 60
12 times 5= 60
Therefore, a equals 7
For this case we have the following system of equations:

Equating the equations we have:

To find the solutions we factor the equation. To do this, we look for two numbers that, when multiplied, result in -3 and when added, result in -2.
These numbers are: -3 and +1

Thus, the factored equation is:

Then, the solutions for the variable "x" are:

We find the solutions for the variable "y":

Thus, the solutions are:
