If a rectangle is graft on a coordinate plane so that has horizontal and vertical sides, how can you find the rectangles perimeter?

You count the lines between the sides.

Step-by-step explanation:

By counting the lines between each side you should get a number. Then you can do actual perimeter.

the solution is x<4 (color green)

Step-by-step explanation:

hello :

draw the graph for the line : y= x-13 ( color bleu)

draw the graph for the line : y= -4x+7 ( color red)

the solution is x<4 (color green)
