-The perimeter is the length of the line if the whole rectangle was straightened out. -a rectangle has 2 sets of 2 even sides. The top and bottom width would be equal and the two heights would be equal
Armed with these two facts we know the perimeter would be Side A + Side B + Side C + Side D 9.35 + 9.35 + 6.82 + 6.82 = ?
The actual formula for a rectangle or even a square is 2(length + width)
20.8478066 (or 20.85%) you do 480.77 minus 380.54 and it comes out to 100.23 and then you do 100.23/480=x/100 (discount/original=percent/100) and you multiply 100.23 by 100 and it comes to 10023 and you do 10023 divided by 480.77 and it comes out to 20.8478066 or 20.85%
