Lisa wants to make a square quilt that has an area of 64 square feet.
How long is each side of the quilt?
How many inches in length is each side?
If each side was 1 foot shorter, what would be the length of each side?
Area = side^2
So
64 = side^2 take the square root of both sides
8 (ft) = side
8 ft = 8*12 = 96 inches
If each side was 1 ft shorter = 7 ft on a side
