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
