Here is the first sign that should tell you this isn't a rectangle.
d=_/w^2+l^2 is the equation to solve the diagonal of a rectangle
if you plug in 21 and 20, d would equal 29 not 28 so for that reason alone it is not a rectangle.
I am about 90% sure the correct answer is B. I hope this helps let me know if I was right.
Option B!
The unknown number is 48 using the equation: x ÷ 12 +49=53 subtract 49 from both sides and get x ÷ 12 = 4 multiplying by 12 on both side to get rid of the ÷12 and get the final answer of x=48.
It really depends what situation you are trying to set goals at,
Trying to understand math concept or any really concept, I would set little goals such as " Study for 15 mins a day" or something and the big goal would be "UNDERSTAND THE CONCEPT"
for goals, I would set small goals that work towards your main goal.
