What is the perimeter of this rectangle?

a.
19 m

b.
21 m

c.
38 m

d.
70 m

In perimeter, you add up all the sides.

So let's first start adding to of the sides, and then the other two, since there is a total of 4 sides.

Two sides are the same, and the other two are also the same.

This means that two sides must be 14 m and another two sides must be 5 m.

Now that we know the length of all the sides, let's add up all the numbers.

5 + 5 = 10

14 + 14 = 28

10 + 28 = 38

The perimeter of the rectangle is 38m.

The answer to your question is option C. 38 meters.

I hope this helps! :)

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
