Answer:
area is length * width, so
5x10^5 * 4x10^4
multiplication is commutative, so that's
5*4 * 10^5*10^4
= 20 * 10^9
= 2*10^10 m^2
if the powers stuff is confusing, it's just shorthand for multiplication
10^5*10^4 = (10*10*10*10*10)*(10*10*10*10) = 10^9
just as multiplication is shorthand for addition
5*4 = 5+5+5+5

it is NOT A or C i can tell you that
The three inside angles of a triangle equal 180 degrees,
If one angle is 110, subtract that from 180 to find the total of the other two.
180 - 110 = 70
The other two angles equal 70 degrees.
809 * 56 =
Simply use your calculator.
