you are desighning a poster that would be 3yd wide and 8 feet high. how much paper do you need in square feet. please explain

3 yards = 9 feet

9*8 = 72 square feet

but the book says 74. why ois that?

beats me

To calculate the amount of paper needed, we need to find the area of the poster in square feet. Since we are given the width in yards and the height in feet, we need to convert them to the same unit before performing the calculations.

1 yard = 3 feet

So, the width of the poster in feet would be:
3 yards * 3 feet/yard = 9 feet

Now, we can calculate the area of the poster by multiplying the width and height:
Area = Width * Height
Area = 9 feet * 8 feet
Area = 72 square feet

Therefore, you would need 72 square feet of paper to design the poster.
