The sides are in a ratio of 4 : 1, so if the length of
WXYZ
is
x
then the length of
ABCD
is 4
x
, and if
the width of
WXYZ
is
y
then the width of
ABCD
is
4
y
. Then the areas are in a ratio of

. The ratio is still 4 : 1.
55.
The ratio of the areas is still 16 : 1 since the ratio
of the sides is still 4 : 1.
56.
No; the corresponding sides are not in proportion.
The ratio of the widths is 1 to 1 but the ratio of
the heights is 2 to 1.
57.
The widths are the same but the height of the
36% rectangle is twice the height of the 18%
rectangle, so the ratio of the areas is
