¨        2D –geometric shape:  square, rectangle, triangle, circle, trapezoid, parallelogram, etc.

 

 

 

 


¨        composite figure:  a combination of 2 or more geometric shapes     e.g.                              e.g.

 

 

¨        3D –geometric shape:  rectangular prism,    triangular prism,    cylinder,    cone,    sphere,     pyramid,   etc.

 

 

 

 

 


¨        Calculate the Perimeter of a Rectangle:   distance around the rectangle (add up the lengths of all 4 sides)

 


                                                                      P = L + L + W + W        or         P = 2L + 2W       or        P = 2(L + W)

 

 

 

 

¨        Calculate the Area of a Rectangle:   number of square units that it covers (multiply length x width)

 

                                                             A = L x W

 

¨        Calculate the Perimeter of a Square:   distance around the square (add up length of all 4 sides)

 

                                                                 P = L + L + L + L        or         P = 4L

 

 

 

¨        Calculate the Area of a Square:   number of square units that it covers (multiply length x length)

 

                                                         A = L x L        or       A = L2

 

 

¨        Calculate the Perimeter of a Triangle:   distance around the triangle (add up the lengths of all 3 sides)

 


                                                                  P = a + b + c

 

 

 

¨        Calculate the Area of a Triangle:   number of square units that it covers ( ½  x base of triangle x height of triangle)

 

                                                                                               A =            A =

 

 

¨        Calculate the Circumference of a Circle:   distance around the circle  (the “perimeter” of the circle)

 

r

 

                                                                       C = 2r                      or                                C = d

                                                                             (r  is  radius)                                         (d  is  diameter)        

 

 

 

¨        Calculate the Area of a Circle:   number of square units that it covers (  x  radius  x  radius)

 

                                                       A = r2           A =  x r x r

 

¨        Calculate the Surface Area of a Rectangular Prism:  add up the areas of all 6 sides of the prism

                                                                                       SA = (2 x L x W )+ (2 x L x H) + (2 x W x H)

                                                                                       or  SA = 2(LW + LH + WH)
