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
The correct answer is C. Hope this helps.
For this the aweswer is f
I think they both go into 10,000 bases of the calculations from the calculator on my phone
Answer:
It would've been more difficult to solve and doing it as shown in EX:2 it's a way easier method to use and remember.
