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

A. 30 cm2
B. 12.5 cm2
C. 25 cm2
D. 50 cm2

C. 25 cm2

Since the height is 5 cm and the length is twice the height (10 cm), the area of the rectangle is calculated by multiplying the height by the length:

Area = 5 cm * 10 cm = 50 cm2

Therefore, the correct answer is 50 cm2.
