What is the area of the rectangle?

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

We have:

20 blocks = 1 mile

1 block = 1/20 miles = 0.05 miles

Length of 3 blocks = 3×0.05 = 0.15 miles

Length of 4 blocks = 4×0.05 = 0.20 miles

Area of the Orchard Hill = 0.15×0.20 = 0.03 square miles

Thus, the area of the Orchard Hill is 0.03 square miles if the length of each block is the same and the length of 20 blocks is 1 mile, option (A) is correct.
