Sometimes scale drawings are shown on graph paper. Each square on this graph paper is 1/4 inch. Use the scale drawing of the living room to answer each question. There are 1,296 in.2 in one square yard. Use a proportion to find out how many square yards of carpet it would take to cover the floor.
There are 12 squares wide and 10 squares high... I have no idea how to do this....help
28 yd2
30 yd2
32 yd2
35 yd2

You haven't said what the scale is. what are the dimensions of the room represented by a 10x12 square grid?
If each square represents a foot, then a 3x3 block of squares represents a square yard.
Once you figure out how many inches of the room are represented by a square on the paper, then you can do some math. 
The scale is 1/4

10/12=x/36
360/12=30 yds
1296 inches converted into yards is 36 yds 
The answer is 30
