x1 = 2
x2 = -6
y1 = 3
y2 = 4
Length of first side :
a = x1 - x2
a = 2 - ( - 6 )
a = 2 + 6 = 8
Length of second side :
b = | ( y1 - y2 ) |
b = | 3 - 4 |
b = | - 1 |
b = 1
P = 2 ( a + b )
P = 2 ( 8 + 1 )
P = 2 * 9 = 18
Remark :

mean absolute value
Rectangle side is represented by (2,3) and (-6,4). Find the perimeter of rectangle.
Could someone please help~

Thank you for answering.
Don't I have to find the magnitude then use square root of the answer and multiply by 2? If so, could you show it.
