Answer:

#~~11.55# in estimation, #11.53# actual.

Explanation:

Given: #sqrt(133)#

We have:

#133=7*19#

Using approximation,

#sqrt(133)#

#=sqrt(7)*sqrt(19)#

#~~2.65*4.36#

#~~11.55#

Using a calculator, I get #11.53# however.

Note that I only took the principal square root, which is usually used.
