#(sqrt(9025))^2=9025#

Explanation:

Breaking the question down into its component parts:

The square root of #" "..................sqrt(?)#

9025mm #" "...............................sqrt(9025)#

squared #" "..............................(sqrt(9025))^2#
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This is the same as #sqrt(9025)xxsqrt(9025)#

Lets compare this to a known case:

Consider the value of 4

We know that #sqrt(4)=2#

So if we square 2 we get #2^2=4#

Thus #(sqrt(4))^2=4#

Using the above logic we have:

#(sqrt(9025))^2=9025#
