B. 30 cm squared
Since the height is 5 cm, the length of the rectangle is twice that, which is 10 cm.
The area of a rectangle is calculated by multiplying the length by the height, so in this case:
Area = length x height
Area = 10 cm x 5 cm
Area = 50 cm squared
Therefore, the area of the rectangle is 50 cm squared.
