What is the perimeter of a rectangle with the of 10cm and width 20cm <br><br>

natima [27]

Your answer would be 60 cm

Perimeter is when you add all sides together.

Length = 10 cm
Width = 20 cm

There are 4 sides and 2 of each has the same measurements.

So:

L = 10 x 2 = 20

W = 20 x 2 = 40

Add them.

40 + 20 = 60

Estimate of the standard error of the mean = 0.38 lb

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 10.87 lb

Sample size, n = 131

Standard deviation, σ = 4.31 lb

We have ti find the estimate of the standard error of the mean.

Formula for standard error:

$S.E= \dfrac{\sigma}{\sqrt{n}}$

Putting values, we get,

$S.E = \dfrac{4.31}{\sqrt{131}} = 0.3766 \approx 0.38$

0.38 lb is the standard error of the mean.
