Find the perimeter of a rectangle with length 210 meters and width 72 meters

564 meters

Step-by-step explanation:

Perimeter is the total length of the sides of the shape.

The formula for finding the perimeter of a rectangle is (length + width) x 2.

(you can also get the same answer by adding the 4 sides of the rectangle, which is length+length+width+width)

Plug in the numbers.

(210 + 72) x2

= 564 meters

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%
