Question

the diagonal of a small square table top is 30 inches long what is the length each tabletop in inches

Answer 1

If the diagonal of the square is 30 inches long.

We have that x^2 + x ^2 = 30 ^2

2 x^2 = 900

Divide both sides by 2, we have:

x ^2 =450

square root both sides, we have:

x = 21. 2 inches
