Answer:
Correct answer: D = (1, 2) ; A = 16 units²
Step-by-step explanation:
Given:
A (1, - 2), B (5, -2), C (5, 2) D (?, ?)
If the square is drawn in the Descartes coordinate system, the coordinates are of the fourth vertex D (1, 2)
If we subtract the coordinates on the x axis
5 - 1 we get side of the square a = 4
The formula for the area of a square is:
A = a²
A = 4² = 16 units²
A = 16 units²
