A farmer has 1620 yd of fencing to enclose a rectangular pasture for her goats. Since one side of the pasture borders a river, that side does not need to be fenced. The sides of length a must be four times as long as side b. Find the dimensions of the rectangular pasture.

the length of b is ___ yards
the length of a is ___ yards

0.16 or 16%

step-by-step explanation:

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
