The width of a large, rectangular prism-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?

As we know the area of rectangle is the product of its width and length.

Suppose if Length = a and Width =b then area of the rectangle is

Area of Rectangle  = Length x Width = a x b

Now as given in the question, Width = 1.9 km and Length = 4.4 km

Area of Rectangle = 4.4 km x 1.9 km = 8.36 square kilometers
