___??____ inches


Please help me idk what to do

Answer 1

divide 252 by 21.
21 times 12 = 252
12 is 9 units shorter than 21.
so the answer is 12 inches by 21 inches
you work backwards from the area
area = width times length
a = wl
we know w is 9 units shorter than the length
so now we have the equation 252=(l-9) times l
plug in 21 for l and then solve there is your answer.
