Answer to Zoe's Border

Since the length of Zoe’s blanket is 6 yards, the width is 2, because 2x3=6.  You can use an equation to solve for the width:

Length=3 x width

6=3w

6=3(2)

Since the width is 2 yards and the length is 6 yards, we use our perimeter formula to find the distance around the blanket:

(2xlength)+(2xwidth)=perimeter

(2x6) + (2x2)= p

12+4=P

P=16 yards

Since Zoe is putting border around both sides of the blanket, we must multiply the perimeter by two to get 32 yards, so:

Length=6 yards

Width = 2 yards

Perimeter= 16  yards

Total Ribbon Needed= 32 yards
