    i can tell you the method

    25 x 25=   _ _ _ _

    if both nos. are ending in 5, then last two nos. are 25

    so, ans= _ _ 25

    the first digit of the numbers is 2

    so, the first nos. of answer is 2 x (2+1)= 06

    so, the answer is 0625

    you can do the rest by the same method
