To estimate the number of square feet in 35 square miles, we'll first round the number of square feet in one square mile to the nearest ten million.

Since there are 27,878,400 square feet in one square mile, rounding to the nearest ten million would give us 30,000,000 square feet in one square mile.

Next, we'll round the number of square miles to the nearest ten. Since we're starting with 35 square miles, which is already rounded to the nearest whole number, we don't need to make any adjustments.

Now, let's multiply these estimates:

Estimated Answer = (Estimated Square Feet in One Square Mile) * (Estimated Square Miles)
= (30,000,000 square feet) * (35 square miles)
= 1,050,000,000 square feet

Thus, the estimated answer is that there are approximately 1,050,000,000 square feet in 35 square miles.

For the exact answer, we'll calculate it by using the actual number of square feet in one square mile:

Exact Answer = (Number of Square Feet in One Square Mile) * (Number of Square Miles)
= (27,878,400 square feet) * (35 square miles)
= 976,244,000 square feet

Therefore, the exact answer is that there are exactly 976,244,000 square feet in 35 square miles.
