Question

The length of a rectangle is 7 meters less than twice the width. Find the dimensions if the area is 60 square meters.

Answer 1

l = 2w - 7
w = 6

Answer 2

remember that the area of a rectangle is found by\[LxW=A\]where L is the length of the longest side, and W is the width of the other side, since your A=60 you have that\[60=LxW\]now you're told that length is 7 less than than twice the width, so you have that\[L=2W-7\]now you plug in this L into the Area formula to get that\[60=W(2W-7)\]solve for W to get one of your dimensions, then use that W in the and plug it into\[L=2W-7\]to get your L

Answer 3

you're going to have to use the quadratic equation to solve for W, remembering that you can only have positive length
