    The width of the rectangle become 20 cm.
    According to the statement
    we have to find the width of the rectangle.
    So, For this purpose, we know that the
    Rectangle is a parallelogram all of whose angles are right angles.
    According to the information:
    A rectangle has a length of 21 cm and a diagonal of 29 cm.
    Here we use the this formula
    d² = l² + w²
    So, Substitute the values
    29² = 21² + w²
    841 = 441 + w²
    Now, solve it then
    w² = 400
    Solve the square root then value becomes
    w = 20 cm.
    The width of the rectangle become 20 cm.
