Estimate to determine if the answer is a realistic solution. 1.8 times 16.5 equals 29.7

One possible way of estimating an answer to see if it is a realistic solution is rounding up/down numbers with decimals so you can easily guess!

For example, in this problem, lets <u>round 1.8 up to 2 and 16.5 up to 17.</u>

2 × 17 = 34

34 is not that far from 29.7 !

So, we can say that <u>29.7 is a realistic solution</u> considering the inclusions of decimals.

Answer: The pole is 17 feet long

Step-by-step explanation: If Matthew's shadow is 2 feet smaller than his actually size, the shadow of the pole will also be reduced. Since the pole's shadow is 15 feet long, adding 2 will give you its original size, 17 feet.
