Show me the step on how to do this. i know the answer but how do you get it.
a rectangular garden with a 4-feet wide cement sidewalk is shown. the cement for the sidewalk is 1 foot deep.
what volume of cement is needed for the sidewalk?
a) 96 cubic feet
b) 120 cubic feet
c) 192 cubic feet
d) 240 cubic feet

what the question so we can you out

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
