Question

The length of the diagonal of a square is 8 inches.

What is the area of the square?

Answer 1

If the length of a side of a squre is 'a' then
diagonal's length=\[a \sqrt{2}.\]
so side= diagonal/sqrt{2}
So area = (side)^2= (diagonal/sqrt{2})^2.

Answer 2

area=\[(\frac{diagonal}{\sqrt{2}})^2.\]

Answer 3

so the answer is 32 ?

Answer 4

yeah well done:)
