Answer:
18 square units
Explanation:
A square has the following vertices
(−7, −5), (−4, −2), (−4, −8), (−1, −5)
To determine if the are we look for the length of just one of it's sides, because it's a square,all of it's side are equal.
And the are is determined by squaring one of it's sides.
An attachment of the figure is given below to help us know the vertices to use to determine the length.
Length= √ ((-4-(-7))²+(-2-(-5))²)
Length= √((3)²+(3)²)
Length= √(9+9)
Length= √18
So area is the square of the length
Area= (√18)²
Area= 18 square unit
