A square has two parallel sides and four right angles.
2.4 hours
You can get this by setting up the equation:
x/4 + x/6 = 1
Where x is equal to the amount of hours spent working. In this equation x/4 would be Doug. In 4 hours he would paint on room. x/6 would be Elaine. When you add them together using common denominators, you can find x.
The coordinates for this would be : (2, -2)
(6, -2) (6, 4) and (2, 4)
I hope that this helps you !
