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
The answer is 30

bruh your wrong i got 2/5
To determine how many square yards of carpet are needed to cover the floor, we first need to calculate the total area of the floor in square inches. Then, we can convert that value to square yards using the conversion factor provided.
Step 1: Calculate the area of the floor in square inches.
Given that each square on the graph paper represents 1/4 inch, we need to find the area of the floor in terms of these squares.
Width = 12 squares
Height = 10 squares
Total area = Width x Height
Total area = 12 squares x 10 squares = 120 squares
Step 2: Convert the area from square inches to square yards.
Given: 1,296 in.² = 1 yd.²
To convert from square inches to square yards, we need to divide the total area in square inches by the conversion factor.
Total area in square yards = Total area in square inches ÷ Conversion factor
Total area in square yards = (Total area in square inches) / (1,296 in.²)
Using the values calculated in step 1:
Total area in square yards = 120 squares ÷ (1,296 in.²)
Step 3: Simplify the expression.
Total area in square yards = (120/1,296) yd²
Step 4: Calculate the value.
Total area in square yards = 0.0926 yd²
Based on the calculations, it would take approximately 0.0926 square yards of carpet to cover the floor.
Therefore, the closest option to this value is 30 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.
10/12=x/36
360/12=30 yds
1296 inches converted into yards is 36 yds
