What is the perimeter, in inches, of a rectangle whose length is 18 inches and whose area is 216 square inches?
A 60 inches
B 180 inches
c.234 inches
D. 400 inches

A. 60 inches

Step-by-step explanation: 18 x 12 is 216 (area) so 18 + 18 + 12 + 12 = perimeter aka 60 inches.

Linda will have to pay $125.40 for wall-to-wall carpet for her bedroom.

First you had to find the two missing sides. To find the one across the 3m wall, you just needed to do
3 - 0.6 = 2.4 m

To find the one across the 3.6 wall, you do the same thing
3.6 - 1.2 = 2.4

Now that you know all the sides, you times all the sides by 9.50 individually.

Then you add them together to get your answer as $125.40
