A rectangle is twice as long as it is tall. Its height is 5 centimeters.

What is its area in square centimeters? (1 point)

Since the height is 5 centimeters, the length of the rectangle is twice that, which is 2 * 5 = <<2*5=10>>10 centimeters.

Therefore, the area of the rectangle is 10 * 5 = <<10*5=50>>50 square centimeters. Answer: \boxed{50}.
