    The area of rectangle B is 256 cm²

    What is Area of rectangle?

    The area occupied by a rectangle within its boundary is called the area of the rectangle.
    Thus, the formula for the area, ‘A’ of a rectangle whose length and width are ‘l’ and ‘w’ respectively is the product
    Area of rectangle= length  × width.
    It is given that the dimensions of rectangle B are twice times the dimensions of rectangle A.
    Let dimensions of rectangle B are l× B.
    Area of rectangle is
    A= length *  breadth
    Area of rectangle A = 128
    So, Area of rectangle B
    =2( l * B)
    = 2l* 2B
    =2( l * B)
    =2 * 128
    = 256 cm²
    Hence, the area of rectangle B is 256 cm²
