Will mark a rectangle certificate 8 in. by 10 in. will have a frame 1 1/2 in. wide surrounding it. what is the perimeter of the outside edge of the frame?

The perimeter of the outside edge of the frame would be 42in. Considering that the frame adds an extra inch and a half to the rectangle on all sides, you would use the formula P=2(l+w). P is perimeter which is what your solving. This would be solved by first adding 1.5 to 8 to get 9.5 and plugging ll.5 for length and 9.5 for the height. You would get 21, and multiplying 21 by 2 gives you 42.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
