If is a square, where ,
find the ordered pair that represents and then determine the area of the square considering
a unit length cm.
Step 1: Find the ordered pair that represents .
and lie on the same vertical line, so they have the same -value: 7.
and lie on the same horizontal line, so they have the same -value: 5.
Therefore, the ordered pair for is (7, 5).
Step 2: Determine the area of the square.
The side length of the square is equal to the absolute value of the difference between the
-values of a starting point and the ending point.
Then use the formula for the area of a square.
