Let the length of the rectangle be L and the width be
W.
Given that the width is 2/3 of the
length.
Then, we will write:
W
= (2/3)*L................(1)
Also, given that the area of
the rectangle is 96.
Then,
A =
w*L = 96..............(2)
Now we will substitute (1) into
(2).
==> W*L =
96
==> (2/3)*L * L =
96
==> (2/3)*L^2 =
96
Now we will multiply by
3/2.
==> L^2 =
96*3/2
==> L^2 =
144
Now we will take the root of both
sides;
==> L = 12
.
==> W = (2/3)L = (2/3)*12 =
8
==> W = 8.
Now we
will calculate the perimeter;
==> P = 2L + 2W = 2*12
+ 2*8 = 24 + 16 = 40.
Then, the perimeter of
the rectangle is 40 units.
