    B

    Step-by-step explanation:

    Here, we are told that the rectangle is enlarged by a factor of 6, we now want to calculate the new area of the said rectangle.

    Now, for the rectangle to have an area of 20, mathematically the area of a triangle can be calculated using the formula L * B

    where L is the length and B is the breadth

    our product here is 20, so any product that gives 20 would be a good fit as the value of the width and length of the rectangle

    So, let's say the sides measure 5 inches by 4 inches

    Enlarging these by a factor of 6, we have 30 inches by 24 inches

    The new area of the rectangle would thus be;

    30 inches * 24 inches = 720 inches^2
