a rectangle is twice as long as it is tall. its height is 5 centimeters. what is its area in square centimeters

The length of the rectangle would be 2 times its height, so:

Length = 2 * 5 = 10 cm

Now, to find the area of the rectangle, you would multiply the length by the height:

Area = Length * Height
= 10 * 5
= 50 square centimeters

Therefore, the area of the rectangle is 50 square centimeters.
