Answer:
L=36
W=6
Step-by-step explanation:
If the length is six times the width than the width is equal to x. This would make the length 6x or 6 times x. The perimeter of the rectangle is all of the sides added together. So 6x+6x+x+x=14x
The perimeter equals 84 which gives you
14x=84
Divide by 14 on each side and x=6
The length is six times longer than the width which is 6x6 or 36 and the width would just remain 6.
Well, we can simplify 5/10 down to 1/2. See how the top number is the half of the bottom number? You just do the same thing and you get 3/6.
Good luck!

To estimate, you should round some of the numbers to the closest number (rounding up or down). It will be more accurate the less you round. In this problem, we should round -5 1/4 to -5 since it is the closest. -5*-3/2 = 7.7. You will end up with -3/2x (-5 1/4) ≈ 7.5x
≈ means approximately equal.
