Answer:
C
Step-by-step explanation:
I did it by recognizing that they were all powers of two and that exponents add...so we are looking for a standard magic square for the number 0 thru 8, since 1, 2, ..., 256 are the numbers 2^0 thru 2^8...
The numbers are
128, 4, 8
1, 16, 256
32, 64, 2
Each row, column and diagonal's product is 2^12 or 4096.
Good problem
A) By Pythagoras' Theorem x^2 = 13^2 - 5^2 where x = length of the other leg. x^2 = 169 - 25 = 144 so x = 12. cms.
b) perimeter = 5 + 12 + 13 = 30 cms
c) Area of triangle = product of the 2 legs = 5*12 = 60 cm^2.
