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?
2 answers:
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:
Kitchen: 84
Playroom: 63
Dining room: 42
