5mm is NOT TRUE You find it by dividing it by 2

Rectangle Area of parallelogram = Base * Height Area of rectangle = Base * Height

The perimeter is the sum of the four sides. In this case, two sides have 14 cm each, and the other two sides have 5 cm eacn.

Area formulas? Area of a rectangle equals base*height Area of a square equals side*side Area of a triange equals 1/2 * base* height

all you have to do is add together the four sides. 2L+2W=Perimeter (L=length or base, W=Width or height)

Height works out as: 33.7 mm Check: 2*(33.7+71.4) = 210.2 which is the perimeter
