The length of a rectangle is twice its width.
Furkat [3]
The perimeter is the sum of all a shapes sides.

so if length is two times the width, you could write it as 2w.

2w + 2w + w + w = 42. Simplified, it's 6w = 42.
Divide both sides by 6, and you get w = 7.

Since the length is 2w, 2 * 7 = 14, so the length is 14

Area of rectangle is length * width, so do 14 * 7 which is 98. Slap on some units and your answer is 98 sq m

Use the counting techniques from the last chapter. A bag contains three red marbles, four green ones, one fluorescent pink one,
sergiy2304 [10]

Answer:

The probability that she gets all the red ones, given that she gets the fluorescent pink one, is P=0.0035 or 0.35%.

Step-by-step explanation:

Susan grabs four marbles at random.

We have to calculate the probabilities that he picks the 3 red ones, given that she already picked the fluorescent pink.

If it is given that the fluorescent pink is already picked, we are left with three red marbles, four green ones, two yellow ones, and four orange ones. A total of 13 marbles.

The probability that the second marble is red is 3 in 13.

The probability that the third marble is also red is 2 (the red marbles that are left) in 12 (the total amount of marbles left), as there is a picking without replacement.

The probability that the fourth marble is 1 in 11.

Then, the probability that the 3 red marbles are picked, is:

P=P_1\cdot P_2\cdot P_3=\dfrac{3}{13}\cdot \dfrac{2}{12}\cdot \dfrac{1}{11}=\dfrac{6}{1716}=0.0035
