This is an awesome explanation for finding area... (Instantly geeked out because now I can explain this to my 4th grader without struggling) Thanks for usable content!
Thanks for the explanation. My grandson's 4th grade teacher only taught A= LxW and several answers were marked wrong against the answer key because the extra step of finding the difference between the unequal sides was not done. That being said it is very confusing. But if you're building a house it's important to know the precise area, lol 😉
