Let width be x

Length= x+3 

P=2(x+l) 
42=2(x+(x+3))
42/2=2x+3
21=2x+3
21-3=2x
18=2x
18/2=x
9=x

Area=(x)(x+3)
A=(9)(9+3) 
A=108 yards²

Hope I helped :)

A store has 7 red shirts, 15 black shirts, 13
AleksAgata [21]

Answer:First you have to add all of the shirts together, which gives you: 40

Since 15 of those are black, then you need to put those 15 over the total number of 40, making it 15/40.

Then you must simplify by the highest number that will go into both, and since that number is 5, it will then go into 15 three times and it will go into 40 eight times.

That leaves you with the answer of: 3/8

Ilia_Sergeevich [38]

Using sampling concepts, it is found that the correct option is given by:

B. The Golf Federation's conclusion was not valid because the sample was biased since the male customers all lived in California.

<h3>What is sampling?</h3>

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, the objective is to make an estimate about the most popular brand of golf ball from men all over the United States, however, only customers from California were chosen, hence the sample is not representative and option B is correct.
