    Answer:

    h = 10 cm

    Explanation:

    The magnification produced by a mirror is given by :

    m=\dfrac{h'}{h}

    h’ is the image size and h is the object size

    We have, h = 10 cm, m = +1

    So,

    m=\dfrac{h'}{h}\\\\h=\dfrac{10}{1}\\\\h=10\ cm

    So, the size off the object is same as that of the size of the image i.e. 10 cm.
