Answer:
5 large pieces of fabric.
Step-by-step explanation:
Length of each side of a square piece of fabric = yard
Area of a Square = Length X Length
Area of one square piece of fabric = X
=
square yard.
To make one scarf, Doris uses 6 square pieces.
Area of one scarf = square yard
Each large pieces of fabric is one-third yard long and 2 yards wide.
This is clearly a rectangle,
Area of a Rectangle = Length X Width
Area of each large piece of fabric= square yard.
Since the Area of one scarf is equal to the area of each large piece of fabric, in order to make 5 scarves, Doris would need 5 large pieces of fabric.
