Step-by-step explanation:

Perimeter formula:

Given

Substitute l in perimeter formula and solve for w:

Maximum width is 19 feet and the length is 19 + 12 = 31 feet. In this case all fencing will be used.

With l = 31 and w = 19, the area is:

A = 31*19 = 589 square feet:

452,489 to the nearest thousand is 452,000

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

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%
