Sophina bought 3 yards of trim to put around a rectangular scarf. She does not want the scarf to be wider than 12 inches or narrower than 6 inches. Using whole numbers, if she uses all the trim, what are the possible dimensions of her scarf in inches?
6x48,7x47,8x46,9x45,10x44,11x43,12x42
3yd of trim = 3 x 36" = 108" of trim
if it goes around the rectangle, then 108" = the perimeter of the rectangle. So, P = 2L + 2W = 108
Possible sizes are 42" x 12" and 48" x 6"
36 inches=3 yards
36=1,2,3,4,6,6,9,12,18,36
W<12 W>6
oups sorry
36x3=3 yards
