Answer:
rectangular; 32 in²
Step-by-step explanation:
The base is rectangular, because 1 set of sides is longer than the other.
To find the area of the base, multiply 4 by 8 to get 32 in².
(3,21)(5,35)
slope = (35 - 21) / (5 - 3) = 14/2 = 7
possible answers are :
y - 21 = 7(x - 3)
or
y - 35 = 7(x - 5)
or
y - 49 = 7(x - 7)
or
y - 63 = 7(x - 9)
Just invert it like:

There you have your common denominator! Don't forget to multiply the numerator as well.
