emma bought 2 and 1/2 yards of cording for the trim around the edge of square pillow how much will she use for each side of the pillow
To determine how much cording Emma will use for each side of the pillow, we need to find the perimeter of the square pillow. Here's how you can do that:
1. Recall that the perimeter of a square is the sum of the lengths of all its sides.
2. Since a square has four equal sides, we need to divide the total cording length by the number of sides to find out how much cording will be used per side.
Let's calculate it using the information given:
Emma bought 2 and 1/2 (or 2.5) yards of cording for the trim around the edge.
To find the perimeter (P) of the square pillow, divide the total cording length (2.5 yards) by the number of sides (4):
P = 2.5 yards รท 4 = 0.625 yards per side
Therefore, Emma will use 0.625 yards of cording for each side of the pillow.
