Please help I have a test please

16 units

Step-by-step explanation:

this rectangle is nice to us. its side lines are clearly parallel to the coordinate axis.

A starts at x=1, y=2.

B is straight above with x=1, y=7

so, how long is AB ? it is just the difference in y direction 7-2=5.

C is then on the same y height as B, and is just a bit to the right (bigger x value) with x=4, y=7

what is the distance BC ? just the difference in x 4-1=3.

since it is a rectangle, the other 2 sides are a "copy" of these first 2 sides.

so, another 5 and 3.

therefore, the perimeter of the rectangle is

2×5 + 2×3 = 16 units of the coordinate system.

ok then what happened.

my computer is slow i can not see it sorry
