Question

Juana is building a mall with twenty stores, each one is 20 feet by thirty five feet. the mall has one hallway with the dimensions of 100 feet by 20 feet. What is the malls square footage?

Answer 1

20 x 20 x 35 + 100 x 20 =

 

400 x 35 + 100 x 20 =

 

14000 + 2000 =

 

16000

Answer 2

Each store is 20ft by 35ft, and the hallway is 100 ft by 20 ft.

 

20 x 35 = 700 each store

700 x 20 stores = 14000

100 x 20 = 2000 hallway

14000 + 2000 = 16000

 

So the total square footage would be 16,000 square feet.
