Linda plans to put in wall-to-wall carpet in her bedroom. She measures the dimensions of her bedroom and sketches up the floor plan shown below.
The carpet costs $9.50 per square meter.

How much will Linda pay for wall-to-wall carpet for her bedroom? $

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
