I don’t understand, help me out

Mathematics

Answer:

a. 76 b. 52

Step-by-step explanation:

The perimeter of a rectangle is the sum of its four sides.

Now all rectangles have a width and a length.

To find the perimeter it is 2 width + 2 length or 2W +2L.

So if the Perimeter P = 344 and Width W = 76 and P = 2W + 2L

Then...

2(76) + 2L = 344 multiply 2 and 76

2L + 152 = 344 subtract 152 from both sides

2L = 192 divide both sides by 2

L = 96

The length is 96.

The equation of an area of a rectangle is A or  area = width x length or W x L

So the equation is A = W x L

If the area is 4732 and the length is 91 then

91W = 4732 divide both sides by 91

W = 52

The width is 52.

Hope that helps, good luck with your homework!

Charlotte is running at a rate of 9\,\dfrac{\text{km}}{\text{h}}9
finlep [7]
<h3>Answer: Charlotte's speed in meter/second is 2.5m/s.</h3>

Step-by-step explanation:

Given speed of Charlotte in kilometer per hour = 9 km/h

We need to find the Charlotte's speed in meter per second.

We know 1 kilometer = 1000 meter

And 1 hour = 3600 seconds.

Plugging those values of km and hour in given speed in km/h, we get

9\ \frac{km}{h} = 9\times \ \frac{1000m}{3600 seconds}

=\frac{10m}{4s}= 2.5\ m/s.

Therefore,

<h3>Charlotte's speed in meter/second is 2.5m/s.</h3>
