Find the area of a parallelogram with base 15 yards and height 21 2/3

A = 325 yd^2

Step-by-step explanation:

The area of a parallelogram is found by multiplying the base times the height

A = bh

A = 15* 21 2/3

Changing the mixed number to an improper fraction

21 2/3 = (3*21+2)/3 = 65/3

A = 15 * 65/3 = 15/3 *65 = 5*65 =325

A = 325 yd^2

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
