Final answer:
To find the area of the Mega Grand Hotel lobby, which is rectangular, multiply the width (40 feet) by the length (60 feet) to get 2400 square feet.
Step-by-step explanation:
The question is asking us to calculate the area of a rectangular space, which is the product of its length and width. In this case, the Mega Grand Hotel lobby is 40 feet wide and 60 feet in length. The area A can be found by multiplying the width w by the length l. So, A = w × l = 40 ft × 60 ft = 2400 square feet.
