Marcy is sewing a rectangular curtain. The dimensions of the curtain are 171.5cm by 84.3cm. How many square centimeters of fabric does Marcy need?
To find the number of square centimeters of fabric Marcy needs, you can multiply the length and width of the curtain. In this case, the length of the curtain is 171.5 cm and the width is 84.3 cm.
To calculate the area, use the formula:
Area = Length x Width
Substituting the values:
Area = 171.5 cm x 84.3 cm
Multiply the two values together:
Area = 14463.45 cm²
Therefore, Marcy needs approximately 14463.45 square centimeters of fabric for the curtain.
