A rectangle is twice as long as it is tall. Its height is 5 centimeters. What is its area in square centimeters?
The area of the rectangle is 10 cm x 5 cm = 50 square centimeters.
To find the area of a rectangle, we multiply its length by its width. In this case, we know that the rectangle is twice as long as it is tall, and its height is 5 centimeters.
Let's denote the width of the rectangle as "w".
Since the length is twice the height, we can express it as: length = 2 * height = 2 * 5 = 10 centimeters.
Therefore, the length of the rectangle is 10 centimeters, and the height is 5 centimeters.
To find the area, we multiply the width by the height: area = width * height
So, the area of the rectangle is: area = w * 5
Since we don't have the specific value for the width, we can express it as a variable.
Let's denote the width as "w".
The area of the rectangle is then: area = w * 5 square centimeters.
We can't determine the specific area without knowing the width, but we can express it in terms of "w" as area = 5w square centimeters.
