Answer :

Okay, let's break this down step-by-step:

The information provided is:
* The elephant's cage has a rectangular shape
* The dimensions of the cage are:
- 30 feet x 40 feet
- 64 feet x 60 feet

To calculate the area of the cage, we need to multiply the length and width of the rectangle.

For the first set of dimensions:
* Area = 30 feet x 40 feet = 1,200 square feet

For the second set of dimensions:
* Area = 64 feet x 60 feet = 3,840 square feet

Therefore, the area of the elephant's cage is 3,840 square feet.
