WILL MARK BRAINLIEST!!!! 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.
