by

is

with no remainder. Please check the step by step procedures in the picture attached.
We can conclude that:
The quotient of the division is

The remainder of the division is

The divisor is

The dividend is
If the two diagonals are
and
, the are of the rhombus is

So, in your case, the area is

The other options are wrong because:
- option A doens't divide by 2, thus getting twice the area of the rhombus
- option B summed the diagonals instead of multiplying them
- option D took the difference of the diagonals.
3,500 is the best estimate if you multiply 7 by round 456 to 500 so 7x500=3,500
