Question 688397
equation for the area of a rectangle is length x width = area.  now, since the equation states that the width = length - 2, we can easily solve for the length, then substitute to find the width.  First, plug in all of the information given into the area formula, getting length x width = 80.  Now, since we figured out that width = length-2, plug that in, so you will get length x length-2 = 80.  Next, simplify the equation to length^2 - 2(length) = 80.  After, by guessing and checking, you will figure out that length = 8.  Next, since width = length-2, plug in the length value that we already figured out, 8.  So , the new equation is width = 8-2, simplified to width = 6.  Finally, you have figured out length = 8 and width = 6.
