Margot is sewing a ribbon on a seam along the perimeter of a square pillow. the side length of the pillow is 2x2 + 1 inches, and its perimeter is 4(2x2 + 1) inches. if x = 3.5, how much ribbon does she need?

Length of ribbon required = 102 inches

Step-by-step explanation:

Since length of square is given to be  

perimeter of square = 4 x side

Perimeter of given square = 4 ()

for x = 3.5

value of perimeter = 4

                               =4 {2(12.25) +1

                                = 4(24.5+1)

                               = 4 (25.5)

                              = 102 inches

Length of ribbon required = perimeter of Square pillow

therefore length of ribbon required will be 102 inches.
