Question

Find the side of a square whose diagonal is of the given measure. Given = 8 miles

Answer 1

To work this out you need to use the hypotenuse,


`a^(2) + b^(2) = 8^(2)`,
Or simplify to:

`2 * a^(2) = 64`

Which can be halved:

`a^(2) = 32`
Which the root of 32 is 5.7.
So the answer is 5.7 miles.

Hope this helps.

Answer 2

diagonal: d=a√2(a is the side)
8=a√2
a=4√2miles
