# The field

The player crossed the field diagonally and walked the length of 250 m. Calculate the length of the field, circumference if one side of field 25 meters.

Result

a =  248.7 m
o =  547.4 m
S =  6217.5 m2

#### Solution:

$u = 250 \ \\ b = 25 \ \\ a = \sqrt{ u^2-b^2 } = \sqrt{ 250^2-25^2 } = 75 \ \sqrt{ 11 } \doteq 248.7469 = 248.7 \ \text{ m }$
$o = 2 \cdot \ (a+b) = 2 \cdot \ (248.7469+25) = \dfrac{ 2737 }{ 5 } = 547.4 = 547.4 \ \text{ m }$
$S = a \cdot \ b = 248.7469 \cdot \ 25 = \dfrac{ 12435 }{ 2 } = 6217.5 = 6217.5 \ m^2$
