Question

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?

Answer 1

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
