Geometry March 19 th Launch Find the area of the green square, and the inscribed blue triangle. Show all of your work! What is the formula for the area of a rectangle with short sides of B and long sides of C? Inches

Launch Solution Since Area is defined as the product of length and width, we can show our work like this:

Monday Goal SWBAT find the area of parallelograms and irregular polygons. They will be able to explain why they perform each step in the process!!! Today we being our new unit on area and volume. One of our key points for this unit will be using precise units of measurement. Why is this important?

Gardening in the Michigan Spring… Now that the weather has become fantastic, Mr. Harbaugh is beginning to think about gardening. Since he is a teacher, he has a limited amount of money to spend on the wire fencing he needs. To overcome this obstacle, he is forcing his students to help! With only enough money to buy 50 feet of fencing, he wanted his students to make him the largest possible space they could for his garden. Below are the 4 best entries. Which should he choose? What is the question asking you to find? What information do you have to start with?

the entries… 2 feet This student is clearly just trying to suck up…

Exit Ticket Find the Area of both shapes, using the properties and skills that we learned in class. If you have any questions, raise your hand to get some help!
