What is the probability that a I will randomly draw a girl’s name out of our math bucket?(only count those that are present today) What is the probability that if I put all the months of the year in a hat, I would draw a month that begins with a J? How about an M?

Area of a Parallelogram How does measurement help you solve problems in your everyday life?

 Polygon – a closed figure formed by three or more straight lines.  Parallelogram – a quadrilateral with opposite sides that are parallel and opposite sides the same length.  Rhombus – a parallelogram with four equal sides. Vocabulary Start Up

Area of a Parallelogram  The area A of a parallelogram is the product of its base b and its height h.  A = bh  Model: h b

The area of a parallelogram is related to the area of a rectangle as you discovered in the LAB! Base Height The base of a parallelogram can be any one of its sides. The height is the perpendicular distance from the base to the opposite side

TRUE OR FALSE Parallelograms include special quadrilaterals, such as rectangles, squares, and rhombi.

Find the area

Find the area of the parallelogram  Remember that A=b x h 20 cm 11 cm 13 cm

 A formula is an equation that shows a relationship among certain quantities.  To find missing dimensions, use the formula for the area of a parallelogram.  Replace the variables with the known measurements.  Then solve the equation for the remaining variable. Find Missing Dimensions

 A = bhArea – 45 inches squared Base – 9 inches  Find the height Find the missing dimensions of the parallelogram
