Sum of all interior angles = (n-2)x180, n being the number of sides.
sum of all interior angles = (n-2)x180
sum of all interior angles = (14-2)x180
sum of all interior angles = 12 x180
sum of all interior angles = 2160°

Answer:
Width=13 Length=25
Step-by-step explanation:
The total perimeter of the field is 76 feet.
Lets say that is length is X and the width is Y.
The equation would be:
2Y+2(12+Y)=76
First solve for the parenthesis.
2Y+24+2Y=76
76-24=52
52=4y
y=13
To check your answer, 13 times 2 (26) plus 25 times 2 (50)= 76 so we know this is correct.
