Question

Ingrid is making a quilt using squares that measure 5 in. on a side. What is the length of a diagonal of one of the quilt squares? Round to the nearest tenth please.

Answer 1

If the side of a square is x units long, then the diagonal is x*sqrt(2) units long.


In this case, x = 5, so the diagonal is 5*sqrt(2) units long exactly


Use a calculator to get 7.071 which rounds to 7.1

Answer 2

Thank you so much! x
