The formula to find the perimeter of a rectangle is P = 2(l + w), where p is perimeter, l is length and w is width,
The length of the playground is 16 yards, and the width is 20, because 16 x 20 = 320 and 16 + 4 = 20.
P = 2(l + w)
P = 2(16 + 20)
P = 2(36)
P = 72.
The perimeter is 72 yards.
Hope this helps!!
It could be 10 which would make the triangle a right triangle, since the values follow the Pythagorean theorem (a^2+b^2=c^2)
3/4th of the bottle of juice would be splitting up the 16 oz bottle into 4th, so 16 divided by 4 equals 4. Then because he only drank 3/4th of the bottle multiply the 4 by 3 equaling 12. Then subtract 12 from 16 and you get a total of 4 oz left!!!
