    Yes, there is enough wrapping paper

    The area of the wrapping paper is greater than area of the gift

    Step-by-step explanation:

    What to do is to check the area of the wrapping paper and the gift if equal.

    Looking at the dimensions of the gift, it is a cuboid

    Area of a cuboid = 2 (lb + lh + bh)

    where l, b and h are 50, 35,5 respectively

    = 2 (250 + 175 + 1750)

    = 4350 cm^2

    The area of the wrapping paper is just the product of its side = 75 * 60 = 4500 cm^2

    We can see clearly that the area of the wrapping paper is greater than area of the gift.

    so we can conclude that it is enough to wrap the gift
