Question

A square originally starts with an area of 64 cm. If each side of the square is increased by 2 cm, what is the area of the new square?

A. 68 cm²
B. 72 cm²
C. 81 cm²
D. 100 cm²

Answer 1

The area of the new square is 100 cm².

Step-by-step explanation:

To find the area of the new square, we need to calculate the length of its side. The problem states that each side of the square is increased by 2 cm. Since the original square has a side length of 8 cm, the new square will have a side length of 8 cm + 2 cm = 10 cm. To find the area of the new square, we square the length of its side: 10 cm x 10 cm = 100 cm².
