1 Geometry and the Coordinate Grid SWBAT use the coordinate grid to find polygon’s area and perimeter.

2 1. The dimensions of Joe’s rectangular garden are 18 feet by 12 feet. Joe wants to conduct an experiment to determine whether using fertilizer in the garden makes a difference. The fertilizer costs $0.45 per square foot of ground covered. How much will it cost to cover half of the garden with fertilizer? A) $216.00B) $97.20C) $48.60D) $24.30 2. A right triangle has measurements of 8 in., 15 in., and 17 in. What is the area of the right triangle? A) 60 sq inB) 68 sq inC) 120 sq inD) 136 sq in 3. A middle school is selling rolls of wrapping paper for a fundraiser. The school earns $5.00 for each roll of wrapping paper sold. If the school needs to raise $3,000, what is the minimum number of rolls of wrapping paper that need to be sold? 4. Where is the point x located on the number line? -3 x-2-101

4 Plotting Points Plot the following points and connect them in the order given. Use the coordinates to find the length of each side. A (4,2)B (-2, 2) C (-2, -2)D (4, -2)

5 Plotting Points Plot the following points and connect them in the order given. Use the coordinates to find the length of CD. A (6, 8)B (-3, 8)C (-3, -1) D (6, -1)

6 Polygons on the grid Plot the following points and connect them in the order given. What is the coordinate of a fourth point that would create a rectangle? W (5,6) X (-6, 6) Y (-6, 0)

7 Question 1 Plot the following points and connect them in the order given. What is the length of AD? A (-1, -2) B (-5, -2) C(-2, -4) D(-1, -4) 2 units

8 Question 2 Find the area of the shape given its coordinates. L (-1, 1) M (-1, -5) N (4, -5) O (4, 1) 30 square units

9 Question 3 Plot the following points and connect them in the order given. What is the coordinate of the fourth point that creates a parallelogram? Q (4, 4) R (0,4) S (-1,1) (3,1)

10 Question 4 Plot the following points and connect them in the order given. What would be the coordinates of a third point that would form a right isosceles triangle? E (2, 2) F (2, -2) ( 6, 2) or (6, -2) or (-2, -2) or (-2, 2)

11 Question 5 Find the perimeter of the shape given its coordinates. S (5, -5) T (1, -5) U (1, 3) V (5, 3) 24 units

12 Exit Ticket Without plotting the points given, find the area of the shape given its coordinates. L (-1, 1) M (-1, -5) N (4, -5) O (4, 1) Explain, in words, how you found your solution
