Perimeter & area presentation

  1. 1. Mrs. Brenda Rodriguez 5th and 6th Grade Math
  2. 2. Menu • Objectives • Instructions • Theme: “Perimeter and Area” • Activities • Glossary
  3. 3. Objective • Finding the perimeter and area of a rectangle and square using formulas.
  4. 4. Instructions • Find the perimeter of rectangles and squares with the given dimensions. • Find the area of rectangles and squares with the given dimensions.
  5. 5. • Perimeter is the distance around a figure. For a figure with straight sides, the perimeter is the sum of the lengths of the sides. Perimeter is measured in linear units such as ft., cm, m, Km, in. • Area is the number of square units needed to cover a figure. Area is measured in square units such as square centimeters (cm2) or square inches (in2).
  6. 6. Perimeter Formulas • The perimeter of some polygons can be given as a formula. • The sides of a square are the same lengths. The perimeter equals 4 time the lengths of a side(s). • Perimeter of a square: s + s + s + s = 4 x s = P= 4s s s s s
  7. 7. • The opposite sides of a rectangle are the same length. The perimeter equals 2 times the length (l) plus 2 times the width (w). • Perimeter of a rectangle: P = 2(l + w) l w = w width I = length
  8. 8. Perimeter Activity • The Parks Committee wants to choose the land with the largest perimeter. Find the one they should choose. w = 110 ft. l = 240 ft. s = 165 ft. Park A Park B
  9. 9. • The area of a shape is the amount of space it covers. • One way to measure the area of a shape is to count the number of squares units it covers. Area Formulas
  10. 10. • To find the area of a square or rectangle using formulas is to multiply the length by the width. • Area of a square = side x side = s x s = s2 • Area of a rectangle = length x width = l x w = lw
  11. 11. Area Activity • Find the area of the shapes: 10 cm 3 cm A. 13 cm2 10 ft. B. 26 cm 2 C. 30 cm2 A. 10 ft2 B. 100 ft2 C. 20 ft2
  12. 12. • Polygon – A geometric figure made up of three or more line segments that intersect only at their endpoints.
