Answer:
360 feet long.
Step-by-step explanation:
We have been given that a football field is 100 yards and also includes two end zones that are 10 yards long each.
Let us find the length of both end zones by multiplying 10 by 2 as field includes to end zones.
[tex]\text{The length of both end zones}=2\times 10\text{ yards}[/tex]
[tex]\text{The length of both end zones}=20\text{ yards}[/tex]
To find the total length of football field we will add the length of both end zones to the length of football field.
[tex]\text{The total length of football field including the end zones}=(100+20)\text{ yards}[/tex]
[tex]\text{The total length of football field including the end zones}=120\text{ yards}[/tex]
Let us convert 120 yards to feet by multiplying 120 by 3 as 1 yard equals to 3 feet.
[tex]\text{The total length of football field including the end zones}=120\text{ yards}\times \frac{3\text{ feet}}{\text{yard}}[/tex]
[tex]\text{The total length of football field including the end zones}=120\times 3\text{ feet}[/tex]
[tex]\text{The total length of football field including the end zones}=360\text{ feet}[/tex]
Therefore, the football field is 360 feet long including the end-zones.
