Answer:
she needs 169 square feet of carpet for the room
Explanation:
First of all, note that a square has 4 equal sides
Hence, length of the room = 13 feet
area of the room = square footage of carpet needed
Area of a square = Length × Length
square footage of carpet needed = 13 × 13 = 169 square feet
∴ she needs 169 square feet of carpet
