Question

You have 120 pieces of fabric to make a blanket. Each piece of fabric is a square with a side length of 6 inches. You use as many pieces of fabric as possible to create a square blanket.

What is the area of the blanket?


How many pieces of fabric are left over?

How many more pieces of fabric would you need to increase the size of the blanket?

Answer 1

lets check how many pieces would the blanket use

√(120) = 10.95
this means that we well only use 100 pieces for a square blanket

the area would be 60in*60in = 3600 inches

as 10.95 is really close to 11 lets check how many are left for a 11*11 pieces blanket

11*11 = 121
if we would have one more piece then the blanket would be bigger.
