A city block is a square with each side measuring 104yrds. Find length of diagonal of city block.

The length of the diagonal is approx how many yards?

The diagonal of square we will calculate by using Pythagoras theorem:

d^2 = a^2 + a^2

d^2 = 2a^2

if we square root each side we get:

d = a√2

Now we calculate d by expressing a value:

d = 104*√2 = 147.078 yards

rounded the answer is d = 147 yards
