Question

a side of a square bulletin board measures 34 inches. Which of these is the closest length of a diagonal?

Answer 1

If you diagonally slice the board, you get a right angle, which pyth thm can be used. side2 x side2 = diagonal2

34squared + 34squared = x (diagonal) squared
1156 + 1156 = x squared
2312 = x squared
x = 48.0832611207
so just correct it to the closest as 48 inches
