1. Calculate the perimeter of a regular octagon with sides equal to 6,7 cm. 2. Calculate the length of a rectangle if its area is equal to 151,38 m and its breadth is 8,7 m. 3. The floor of a room 4,5 m by 3,75 m has to be covered with square carpet tiles with sides equal to 750 mm. Calculate: a) the area of the floor in m b) the area of a tile in mm c) the number of tiles you will need to cover the floor d) the cost to tile the floor at R82,50 per square metre. 4. Calculate the area of the following shape (draw sketches to show how you divided it up): 5 cm 8 cm 7 cm 5. Complete the table: Shape Measurements Perimeter a) Square Side = mm (1) Polygon (2) Hexagon (3) Quadrilateral (4) Pentagon b) Rectangle Length = 26 mm Width 1,7 cm mm 23,6 cm 5. The perimeter of an isosceles triangle is 450 mm. One of the equal sides measures 190 mm. Find the length of the third, unequal side. are the perimeter of kite ABCD where AB = 29 cm and CD = 47 cm. 3. match the terms in Column A with the definitions in Column B. 9 Convert these measurements to centimetres: a) 3,1 mm 10. Convert these measurements to cm: a) 721 mm c) Regular pentagon Side = B b) 0,0012 km 875 mm (a) Polygon with six sides (b) Polygon with five sides (c) Geometric shape in a plane bounded by straight nes (d) Polygon with four sides b) 2,006 m cm d) Kite Side 1 = Side 2=2,6 7,8 cm Total
