Similarities between Rectangle & Parallelogram:
both are quadrilaterals
opposite sides of both shapes are parallel to each other
both have four sides (four-sided figure)
opposite sides of both shapes are of equal length
To find the perimeter of a rectangle, just add up all the lengths of the sides:
Perimeter = L + w + L + w
= 2L + 2w
To find the area of a rectangle, just multiply the length times the width:
Area = L x w
To find the perimeter of a parallelogram, just add up all the lengths of the sides:
Perimeter = a + b + a + b
= 2a + 2b
To find the area of a parallelogram, just multiply the base length (b) times the height (h):
Area = b x h
