A designer places 4 identical squares on a surface and spaces them 3 5/16 inches apart. Each square is 7 1/4 inches wide. If you lay 12 squares horizontally in a row, what is the total distance across the squares?

Sagot :

Number of spaces would be number of squares - 1

You would have 12 squares and 11 spaces.

Multiply number of each by their size then add the two together:

12 x 7 1/4 = 87 inches

11 x 3 5/16 = 36 7/16 inches

Total = 87 + 36 7/16 = 123 7/16 inches

Answer: 123 7/16 inches
