if the side lengths of a rectangle are a and b
then A = a * b
If it is really a square then b = a
then
A = a^2
I have some questions I have to answer can I get a formula for to find the diagonal length of any paper square? (it’s a project.)
4 answers
and
d^2 = a^2 + b^2
so
d = sqrt (a^2+ b^2)
and
if really square b = a
and
d = a sqrt 2
d^2 = a^2 + b^2
so
d = sqrt (a^2+ b^2)
and
if really square b = a
and
d = a sqrt 2
Thanks!
You are welcome.
