5. 1,000,000   Because the digit to the right of the hundred thousand's digit is a 9, you need to round it up. Since the number is 900,000, however, you should round it to 1,000,000

6. 9,300   The digit to the right of the hundred's place is 5, so round the 2 up to a 3.

7. 5,070   The digit to the right of the ten's place is 8, so round the 6 to a 7.

8. 5,280   The digit to the right of the ten's place is a 2, so keep the 8 the same and change the 2 to a 0.

Some basic rules to remember about rounding:
1. If the digit to the right of the place you're rounding is greater than 5, increase the number by 1 and change all digits to the right to 0.
2. If the digit to the right of the place you're rounding is less than 5, keep the digit the same and change all digits to the right to 0.
3. If you're rounding 9 up, carry 1 over to the next place to the left. For instance, when rounding 987 to the nearest hundred, you would round up the 9 because 8 is greater than 5. The answer would be 1,000, because you have to carry the 1 over to the left.

Recall that area of the triangle is 1/2*(base)*(height)1/2*(13)*(17) = 110.5the answer is 110.5
