Not sure what the length of the rectangle is but to find perimeter of a rectangle you can use the following formula

2w+2l= perimeter

The reason we multiply both the length and width by two is because there are two ends of the width and two ends of the length.

The other formula that would also work is as follows

w+w+l+l= perimeter


Hope it helps

A bag contains 6 blue balls, 3 green balls and 3 yellow balls. What is the probability of choosing one blue ball and then a yell
EastWind [94]
Prob(first ball being  blue) =  6 / (6 + 3 + 3) = 6/12 = 1/2
Prob ( picking a yellow ball) = 3 /12 = 1/4

As the 2 events are independent the probabilities are multiplied 
So the answer is 1/2 * 1/4 = 1/8
