Square diagonal

Calculate the length of the square diagonal if the perimeter is 476 cm.

Result

d =  168.29 cm

Solution:

o=476 cm  o=4a  a=o/4=476/4=119 cm  d2=a2+a2=1192+1192=28322  d=2 a=2 119119 2168.2914168.29 cmo=476 \ \text{cm} \ \\ \ \\ o=4a \ \\ \ \\ a=o/4=476/4=119 \ \text{cm} \ \\ \ \\ d^2=a^2 + a^2=119^2 + 119^2=28322 \ \\ \ \\ d=\sqrt{ 2 } \cdot \ a=\sqrt{ 2 } \cdot \ 119 \doteq 119 \ \sqrt{ 2 } \doteq 168.2914 \doteq 168.29 \ \text{cm}
