Answer:
ab = 280
or
a = 280/b
Step-by-step explanation:
Inverse variation is of the form
xy = k
Since we have a and b as our variables
ab = k
20 *14 = k
280 = k
ab = 280
Sometimes they write it as
a = 280/b
If the rectangles are similar, then the ratio of corresponding sides are in proportion.
12/x = 9/8 where x is the length of the smaller rectangle
Cross multiply to get:
9x = 12*8
x = 32/3 which is 10.67 approx
I believe that the answer is B-144cm^3
