Noah had been preparing to learn yoga all November. He attempted 12 stretches a day. After a month how many stretches had he done?

If Khierra had done half of the stretches that Noah did within a day for the entire month of November, how many stretches had she done?

Noah=360 (12 x 30=360)

Khierra=180  (1/2 of 360=180)

                    (360 divided by 2=180)

                    (6 x 30= 180)

Area and Perimeter

100

A square has a length of 8 and a width of 8. What is the area? What is the perimeter

A= L x W                    P= L+L+W+W

64= 8 x 8                  32= 8+8+8+8         

200

A square has a length of 10. What is the area? What is the perimeter?

A= L x W                    P= L+L+W+W

100= 10 x 10                  40= 10+10+10+10

A rectangle has a length of 10 and a width half of the length. What is the area? What is the perimeter?

A= L x W                    P= L+L+W+W

50= 10 x 5                  30= 10+10+5+5

A rectangle has a length of 3 and a width 3 times the length. What is the area? What is the perimeter?

A= L x W                    P= L+L+W+W

27= 3 x 9                 24= 3+3+9+9

What would the length and width have to be in order for the perimeter to be greater than the area?

Examples: 

A= L x W                    P= L+L+W+W

1= 1 x 1               4= 1+1+1+1

2= 1 x 2               6= 1+1+2+2

4= 2 x 2               8= 2+2+2+2

6= 2 x 3               10= 2+2+3+3

9= 3 x 3               12= 3+3+3+3

12= 3 x 4              14= 3+3+4+4
