1 yard=3 feet
4yards= 4•3= 12 feet
Perimeter of a square = 4•side = 12 so side of the square is 3 feet
Area of square = 3•3=9 Square feet
Answer:
a. 126
b. 15120
Step-by-step explanation:
5 chose 9 = 9 * 8 * 7 * 6 * 5/1/2/3/4/5 = 126
if order matters...
9*8*7*6*5 = 15120
For any polygon the sum of the exterior angles is 360. Since The polygon is regular divide 360 by 12 to get the exterior angle measure. Interior and exterior angles are supplemental so subtract the exterior angle measure from 180.<span>
