What is the length of a diagonal of a square with a side of 8

diagonal is sqrt of (s^2 x 2)

8^2 = 64

64*2 = 128

 round answer as needed

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
