The coordinates below are the three vertices of a rectangle. Identify the fourth coordinate and the area of the rectangle. A (2,1), 24 units squared
B (2, 1), 20 units squared
C(2, 2) 24 units squared
D(2, 2) 20 units squared

(2,2) and 24 units squared

Step-by-step explanation:

A rectangle has all 90° angles

so it must have the same y coordinate as point A and the same x coordinate as point C.

That would give you a point of (2,2)

width = difference in x coordinates of points A and C

Length= difference in y coordinates of points A and B

width=4

length=6

Area =24

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
