1. Do-Now 1)Find the midpoint of the line segment with endpoints A(0, –3) and B(–8, 1). 2)Find the other endpoint of the line segment with endpoint R(1, –6) and midpoint M(–2, 4). 3)Find the distance between (–7, 5) and (1, 8). M(–4, –1) S(–5, –16)

2. Perimeter, Circumference, & Area Square *side length s P = 4s A = s 2 Rectangle *length l and width w P = 2 l + 2w A = l w a b c h TriangleCircle r *side lengths a, b, & c, base b, & height h *radius r P = a + b + c A = bh C = 2 r A = r 2

3. Find the measure of each perimeter (or circumference) and area. Round answers to the nearest tenth where necessary. 1) 2) 3) 4) 10 6 8 4 3 2 7 135 P = 32 A = 60 P = 13 A = 10.5 C = 25.1 A = 50.3 P = 34 A = 60

4. Ex: You have a part-time job at school. You need to buy enough grass seed to cover the school’s soccer field. The field is 50 yds wide and 100 yds long. The instructions on the seed bags say that one bag will cover 5,000 sq. ft. How many bags do you need?
