Answer:

P = 74\ meters

Step-by-step explanation:

By definition the perimeter of a rectangle is the sum of the lengths of its 4 sides.

The formula for calculating the perimeter of a rectangle is as follows:

P = 2w + 2l

Where P is the perimeter, w is the width and l is the length.

In this case we want to find P and we know that:

w =16\ meters

l =21\ meters

Therefore:

P = 2(16) + 2(21)

P = 32 + 42

P = 74\ meters

bogdanovich [222]

Answer:

Third table

Step-by-step explanation:

For the relationship to be proportional

y/x = constant

First table y/x = 8/4 = 2    then 7/11 doesn't =2  so it is not

Second table y/x =52/5 = 5    then 49/7 doesn't =5  so it is not

Third table y/x = 3/6=1/2    then 5/10 = 1/2   then 7/14 = 1/2  it is proportional

Last table y/x = 6/3 = 2    then 11/8 doesn't =2  so it is not
