A. What is the area of the dining room?
B. What is the area of the kitchen?
C. What is the area of the living room?

Answer 1

Answer:

A: 96 B:192 C:288

Step-by-step explanation:

3+2+1=6

Divide 576 by 6 to get 1/6, you will get 96.

so 96 is the area of the dining room.

Multiply 2 times 96, since that would be 2/6.

That would be 192.

So 192 would be the area of the kitchen.

Here's a trick: all you need to do is add 96 and 192 now (or multiply 96 by 3), because that is half of the areas, 3/6.

So 96 times 3 is 288.

The living room is 288.

To check our work, we can add 288 by 96 by 192.

We would end up with 576, which was our original number.

So 288:192:96.
