Area of square with side 7.

Area of square with side 7.

• A. 16
• B. 28
• C. 49
• D. 36

Answer: (C)

The area of a square is the side length squared. With a side length of seven, multiply seven by seven to get forty-nine. The other numbers come from different shapes or different side lengths: 16 would be the area of a square with side 4, 36 would be for a square with side 6, and 28 is the area of a rectangle with sides 4 and 7, not a square. So forty-nine is the correct area.
