  1. Chapter 7: Area By: Brianna Tillery, Troy Jones, and Silvestre Rojas

  2. Area of parallelogram • A four sided plane rectilinear figure with opposite sides parallel. • Area = base x height

  3. If H= 5 and B = 2 what is the area?

  4. Area of rectangles • A plane figure with four straight sides and four right angles • Area = w × l w = width l = length

  5. Width x Length = area • 3.5 cm x 6cm =

  6. Area of squares • A plane figure with four equal straight sides and four right angles. • area = width × height

  7. A x B = Area If a = 15 and b = 7 what is the area?

  8. Area of a Rhombi • Is a convex quadrilateral whose four sides all have the same length • Convex means: curving out or bulging outward • Area = B x H or Area = D1 x D2 / 2

  9. B x h if b = 12 and h = 5 what is the area?

  10. If diagonal 1 = 9 and diagonal 2 = 14 then what is the area?

  11. Area of a Triangle • A polygon with three corners or vertices and three sides or edges which are line segments • Area = ½ B x H

  12. H= 8 and B= 13 • What is the • area?

  13. Area of a Trapezoid • is a 4-sided figure with one pair of parallel sides • Area = ½ x (B1 + B2 ) x H

  14. If b1= 5 and b2= 7 and the • H= 4 then what is the area?
