Question

The first floor of the house consists of a kitchen,playroom,and dinning room. The areas of the kitchen,playroom,and dinning room are in the ratio 4:3:2.The combined area of these three rooms is 189 square feet. What is the area of each room?

Answer 1

4 : 3 : 2

x - area unit

area of the kitchen = 4x

area of the playroom = 3x

area of the dinning room = 2x

The combined area of these three rooms is 189 ft².

Therefore we have the equation

4x + 3x + 2x = 189

9x = 189    |:9

x = 21 ft²

area of the kitchen = 4x = 4(21) = 84 ft²

area of the playroom = 3x = 3(21) = 63 ft²

area of the dinning room = 2x = 2(21) = 42 ft²

Answer 2

Answer:

Kitchen: 84

Playroom: 63

Dining room: 42
