A rectangle is twice as long as it is tall. Its height is 5 centimeters. What is its area in square centimeters?

50 cm to the power of 2

30 cm to the power of 2

25 cm to the power of 2

12.5 cm to the power of 2

Since the rectangle is twice as long as it is tall, its length is 2 times 5 cm which is 10 cm.

The area of a rectangle is calculated by multiplying its length by its width, so the area of the given rectangle is:

10 cm * 5 cm = 50 cm²

Therefore, the answer is 50 cm to the power of 2.
