Answer:
5*10^10.
Step-by-step explanation:

Answer:
60 square feet
Step-by-step explanation:
Area of figure = area of rectangle + area of triangle
Rectangle:
Length = 10 ft
Width = 4 ft
Area = length * width
= 10 * 4
= 40 ft²
Triangle:
Base b = 12 - 4 = 8 ft
Height h = 10 - 5 = 5 ft

= 20 ft²
Area of the figure = 40 + 20 = 60 square feet
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
