Question

if you were given 16 feet by 18 feet how would you graph it on a coordinate plane

Answer 1

You would count 16 positive units on the x axis (starting from the origin) and then count 18 units up from there, drawing a line connecting this point to the x axis. That point would be your outermost corner. Since you were given an area to graph you would draw another line from the outer corner to the y axis and shade that rectangle.

Answer 2

something sort of like that
