5.2.21        V. II . XXIWALT: solve perimeter problems (test base).Steps to success:Understand that perimeter is the distance around a 2D shape.Be able to find the perimeter of a rectangle by using a formula.     (2 x L) + (2 x W)      or   2 x (L + W)Be able to find the perimeter of a regular shape when one length is given (length x number of sides)Be able to find the missing measurement of a rectangle when the perimeter is given.Double the measurement of the side.Subtract the result from the given perimeter.Halve the result to find the measurement of the missing side.
