I have 2 word problems that I think are unsolvable :eek::
1. A garden plot 4m by 12m has one side along a fence. The area of the garden is to be doubled by digging a border of uniform width on the three other sides. What should the width of the border be?
2. Vanessa built a rectangular pen for her dogs. She used an outside wall of the garage for one of the pen sides. She had to buy 20m of fencing in order to build the other sides of the pen. Find the dimensions of the pen if the area is 48m^2 (squared).
PLEASE HELP :)
Thank you :D
EDIT: I have worked at these for about an hour and a half I don't understand a word of this (measurement wise)...
