A rectangle is twice as long as it's tall. Its height is 5 cm. What is the area in square centimeters

1 answer

The length of the rectangle is twice its height, so it is 5 cm x 2 = <<5*2=10>>10 cm.
The area of the rectangle is calculated by multiplying the length and the height, so it is 5 cm x 10 cm = <<5*10=50>>50 square centimeters. Answer: \boxed{50}.
