Question

American football uses a field that is 100.0yd long, whereas the a soccer field is 100.0m long. Which field is longer and by how much( give yards,meter, and percent)

Answer 1

I'm using    1m = 3.28084 ft

1 yd = 3 ft

100 yd = 300 ft
100 m = 328.084 ft   the soccer field is longer
                                    by 28.084 ft
                                    =   9.36 yards
                                    =   8.56 meters    

The percentage of  100m  compared to  100 yd  is the same as
the percentage of  1m  compared to  1yd .

           1m / 1yd  =  3.28084 ft / 3 ft

                            =  1.0936

            The soccer field is  9.36%  longer.

Answer 2

Soccer field is longer than American football field by :

8.56 metres = 9.36 yards

It is about 9.36 % longer

Further explanation

Some units of length and its conversion that need to be recalled are

$1 ~ foot = 30.48 ~ cm$

$1 ~ inch = 2.54 ~ cm$

$1 ~ foot = 12 ~ inches$

$1 ~ mile = 1609.34 ~ metres$

$1 ~ yard = 0,9144 ~ metres$

Let us now tackle the problem !

Given :

American football field → 100.0 yards

$1 ~ yard = 0,9144 ~ metres$

$100 ~ yards = 100 \times 0,9144 = 91.44 ~ metres$

Soccer field → 100.0 metres

Soccer field is longer than American football field by :

$100.0 - 91.44 = 8.56 ~ metres = 9.36 ~ yards$

To find a percentage of the length of the field can be done in the following way:

$\frac{8.56}{91.44} \times 100\% = 9.36\%$
