A rectangular kitchen floor measures 18 feet by 15 feet. A stove on the floor has a rectangular base measuring 3 feet by 4 ​feet, and a refrigerator covers a rectangular area of the floor measuring 4 feet by 5 feet. How many square feet of tile will be needed to cover the kitchen floor not counting the area used by the stove and the​ refrigerator?

Respuesta :

Stove area = 12 square feet
Refrigerator area = 20 square feet
Entire kitchen floor =  270 square feet
12 + 20 = 32 square feet
270 square feet - 32 square feet = 238 square feet
238 square feet will be needed
