You can put this solution on YOUR website! Perimeter is the distance around or the outside distance of the rectangle..
so you would add up all the sides..if the length is 8 and the width 27, then you have 2 lengths and 2 widths, since this is a rectangle.
to solve it would be:
2(8) + 2(27) = x
16 + 54 = 70
so the perimeter is 70
