Answer: 1650 square feet
Explanation:
So we know that the dining room is 28% of the house, and the dining room is 462 feet.
So we know that the house is bigger than 462, so
The whole house > 462 square feet.
That means we have to divide 462 by 0.28 (Since 28% is 0.28)
462/0.28 = 1650
And there you have it.
1650 is way bigger than 462, so it must be it
