Question

Daniel wants to create a banner for his construction business to hang at the house he just built. Daniel will use a single sign that is 42 inches wide by 10 yards long. The sign shop charges based on the square feet. How many square feet does Daniel need to buy?

Answer 1

The solution for this problem is just simple. It tells you to find the area in square feet. Thus, convert the units to feet first. The conversion you need to know are: 12 in = 1 ft and 3 ft = 1 yard.

Width = 42 in * 1 ft/12 in = 3.5 ft
Length = 10 yards * 3 ft/1 yard = 30 ft

Area = Length*Width = 30*3.5
Area = 105 ft²
