This simple problem has a SUPER AWESOME TAKEAWAY!! 
You don't need square roots to find the area of a square given a diagonal. 
Find out how from the "Storm Trooper" teaching the lesson!

Please check out my YouTube Channel "Math Challenge" for the SOLUTION! SCAN that QR Code to take you right to the video!
 
I would be SUPER DELIGHTED AND HAPPILY EMBARRASSED LOL if you showed my video to your class explaining the solution! 

I would LOVE to know how the problem worked out for your kiddos :) 
Any requests for future problems is greatly appreciated!
THANK YOU SO MUCH!!
