Question

the width of a large, rectangular-shaped tree farm is 1.9 kilometers. The length of the farm is 4.4 kilometers. What is the best estimate of the area of the farm ?

Answer 1

The real answer is 8.36, but I think the estimate would be 8.40

Answer 2

Answer:- The best estimate of the area of the farm is 8 kilometers.

Explanation:-

Given:- Width of the rectangular shaped tree farm= 1.9 kilometers

⇒Estimated width of the farm=2 kilometers [2 is the nearest integer to 1.9]

Length of the rectangular shaped tree farm=4.4 kilometers

⇒Estimated length of the farm=4 kilometers [4 is the nearest integer to 4..4]

To make estimates, we usually round the numbers the nearest integer.

Now, Estimated Area of the Farm= estimated width × estimated length

= 2×4 kilometers = 8 kilometers.

∴the best estimate of the area of the farm =8 kilometers.
