You use (y2-y1)/(x2-x1) so if you have two points (ex: (1,2) and (2,4)), plug in those number into the formula
(4-2)/(2-1) = 2/1 = 2 so the slope (or instantaneous rate of change) is 2 for those two points<span />
Answer:
A =256 mm^2
Step-by-step explanation:
The perimeter of a square is given by the formula
P = 4s where s is the length of a side
64 = 4s
Divide each side by 4
64/4 =4s/4
16 = s
To find the area of a square, use the formula
A =s^2
A = 16^2
A =256 mm^2
