A rectangle's width is twice as long as its length. If the perimeter is 36 in., what is the length?

Bumek [7]

Okay here:

Let L be the length and W the width of the rectangle.

1. w=2•L
2. 2L+2W=36

Substitute eq. 1 into eq. 2,

2L+2•(2•L)=36

2L+4L=36

6L=36

L=9

Not done yet, then from eq. 1,

W=2•L
W=2•9
W=18 <------- Your answer. :)

prisoha [69]

Answer:

1568

Step-by-step explanation:

The computation of the minimum sample size is shown below:

Given that

Error E = 11

The population standard deviation $\sigma$ =217

Confidence level 1-α = 95%

Now following formula should be used

n > (Zalpha ÷ 2 × sigma ÷ E)^2

As we know that

Zalpha ÷ 2= 1.96

Now the sample size is

n> (1.96 × 202 ÷ 10)^2

= 1568
