The perimeter, by definition, is the outside measure of that figure. MN and LM are the same length and LK and NK are the same length....we just need to find the lengths! Use the distance formula to find the distance between the 2 points:
$\sqrt{( x_{2} - x_{1} ) ^{2} +( y_{2}- y_{1} ) ^{2} }$
For the segment MN, use the coordinates of M as your x1, y1, and use the coordinates of N for x2, y2:
$\sqrt{(3-2) ^{2}+(4-3) ^{2} }$
which simplifies to
$\sqrt{(1 )^{2}+(1) ^{2} }$ which is $\sqrt{2}$
So that is the length of both MN and LM. So far our perimeter is $\sqrt{2} + \sqrt{2}=2 \sqrt{2}$
Now let's use the same formula to find out the length of one of the longer segments:
$\sqrt{(5-3) ^{2} +(3-2) ^{2} }$
which simplifies down to
$\sqrt{(2) ^{2} +(1) ^{2} }$
which is of course $\sqrt{5}$
Since we have 2 of those lengths, $\sqrt{5} + \sqrt{5}=2 \sqrt{5}$
So our perimeter is, in the end, $2 \sqrt{2}+2 \sqrt{5}$
That's the third choice down

The area of a rectangular rug is 14 1/12 square yards. The length of the rug is 4 1⁄3 yards. What is the width?

Harlamova29_29 [7]

Answer:

w=3 1\4

Step-by-step explanation:

A=LxW

a=14 1\12

l=4 1\3

w=?

14 1\12=4 1\3 x w

14 1\12 divided by 4 1\3=13\4=3 1\4

w=3 1\4

How do you calculate the value of the height, base or width of a rectangle, when the given volume, is 10m^3 and the base is twic

harkovskaia [24]

The length and width of the rectangle is 2√5m and √5m respectively

<h3>Volume of a rectangle</h3>

The formula for calculating the volume of a rectangle is expressed as:

V = lw

where

l is the length

w is the width

h is the height

If base is twice its width, then l = 2w

Substitute

10 = w(2w)

10 = 2w²

5 = w²

w = √5 m

Since l = 2w

l = 2√5m

Hence the length and width of the rectangle is 2√5m and √5m respectively

The temperature dropped 13 degrees in in 7 hours. the final temperature was -2 degrees. what was the starting temperature?

mash [69]

To find this, you'd just add 13 to -2. So -2 + 13 = 11. So the starting temperature was 11 degrees.
