    The new length is 13.5 meters

    Step-by-step explanation:

    Here, we are interested in calculating the new length of the cloth she wants to use

    What we know from the question is that she is making a reduction of 10% from an initial of 15 meters

    Thus, the length she is to use can be calculated by first getting what 10% of 15 meters is

    Mathematically, that would be;

    10/100 * 15 = 1.5 meters

    We now subtract this from the total of 15 meters

    = 15 meters - 1.5 meters = 13.5 meters
