  1. Area of a Rectangle and Area of a Square

  2. For Learning to Happen: • Remove all other thoughts from your mind. • Pay close attention. • Try all the examples. • Ignore all other distractions.

  3. Polygons Polygon: Any straight-sided closed plane figure.

  4. Polygons Polygons come in all shapes and sizes.

  5. # of sides Polygons Name Picture 3 Triangle 4 Quadrilateral Pentagon 5 Hexagon 6 8 Octagon 10 Decagon

  6. Polygons Name The Quadrilateral 1) 2) 3) rhombus rectangle trapezoid 4) 5) square parallelogram

  7. Polygons Name The Quadrilateral The sum of all the angles equals 360º degrees in a quadrilateral. 90º 90º 90º 90º

  8. Polygons Today we are going to find the Area of the Polygons Rectangles & Squares.

  9. Area of a Rectangle • is the number of square units that are needed to cover the surface of a figure. Area height (h) base (b) • How many squares cover this rectangle? • The area of this rectangle is • 12 squares or 12 units squared.

  10. Area of a Rectangle • Label the dimensions of this rectangle. 2 units 6 units • 2 units x 6 units = 12 units2. Area is in units2 because you are multiplying units.

  11. Area of a Rectangle We found the area of the rectangle by multiplying the base times the height. 2 units A = bh 6 units The area of a rectangle is also known as the length times the width. A = bh is the same as A = lw

  12. Area of a Rectangle What is the area of the rectangle? 5 6 5 ft. x 30 ft.2 6 ft. 30 ft2 or square feet

  13. Using The Correct Units • PERIMETER:Is the distance around a figure. • in + in + in + in =in • AREA:Is the square units that cover a figure. • length • width = in • in =in2 • VOLUME:The number of cubic units inside a figure. • length • width •height • in • in • in =in3 squared width length height cubed width length

  14. Area of a Rectangle What is the area of the rectangle? 2 5 2 in. x 10 in.2 5 in. 10 in2 or square inches

  15. Area of a Square A square is a special rectangle. Since the base and the height are the same size, we call them sides (s) instead of base and height. A= s2 s height = s s base = s

  16. Area of a Square What is the area of the square? 4 4 m. 4 x 16 m.2 4 m. 16m2 or square meters

  17. Area of a Square What is the area of the square? 5 5 in. 5 x 25 in.2 5 in. 25in2 or square inches

  18. The End! Area of a Square Take out your study guide!

  19. #1 Area of a Rectangle & Square The Areaof a figure is the number of square units needed to cover it. A = 2 3 6 square units 6 units2 2 3 Square Rectangle 8m 4 8m 5

  20. USING CORRECT UNITS #2 PERIMETER:Is the distance around a figure. in + in + in + in =in AREA:Is the square units that cover a figure. length • width = in • in =in2 VOLUME:The number of cubic units inside a figure. length • width •height in • in • in =in3 squared width length height cubed width length
