* Geometry *

The Perimeter

study hard **

1) The perimeter of any polygon is the sum of its sideslengths

2) The perimeter of the square = side + side + side + side

= (side x 4)

3) The perimeter of a rectangle = Length + Length + width +width

= (Length + Width) x 2

4) The perimeter of a triangle = the sum of its sides lengths5) Find the perimeter of a triangle with sides

lengths 5 centimeters, 9 centimeters and 11centimeters.

Perimeter = 5 cm + 9 cm + 11 cm = 25

cm

6) Find the perimeter of a rectangle of length 8 centimeters,width 5 centimeters.

Perimeter = 8 + 8 + 5 + 5 = 26 cm 5 cmAnother solution:

Perimeter = ( 8 + 5 ) x 2 = 26 cm 8 cm

Unit 3 (Lesson 1)

The Polygon is a closed

plane figure, having

three or more, usually

straight, sides.
