PERIMETER Perimeter is the distance around a figure. To find the perimeter, add the lengths of the sides. MENU

PERIMETER OF QUADRILATERALS MENU 3ft 6ft 2ft + 2ft + 6ft +6ft = 18ft 4m 4m + 4m + 4m + 4m = 16m

PERIMETER OF QUADRILATERALS MENU 3in 4in 5in 4in + 3in + 4in + 5in = 16in 5ft 2ft 3ft + 5ft + 3ft + 5ft = 14ft

AREA Area is the amount of space enclosed by a figure. To find the area of a figure, you count the number of square units in its interior. MENU

AREA OF RECTANGLES MENU 3cm 7cm 3cm 7cm 3cm x 7cm = 21 sq cm 5in 8in 8in x 5in = 40sq in

AREA OF POLYGONS MENU 3cm 5cm 8cm 10cm 8cm x 3cm = 24sq cm 7cm x 5cm = 35sq cm = 59 sq cm 1cm 10cm 7cm 4cm 1cm x 4cm = 4cm 4cm x 7cm= 28cm = 32
