The circle graph shows the rooms in a house and their percentages of the house's total area.
wlad13 [49]

Answer:

2,000 square feet

Explanation:

If the kitchen is 300 square feet, we can divide that by the percentage(15%). We get the answer 20, which will be our conversion factor!

Now, we multiply this conversion factor by all the other percentages(without decimals)

5 x 20 = 100

20 x 20 = 400

30 x 20 = 600

15 x 20 = 300

30 x 20 = 600

Now we add up all of these factors and get the answer :D

100 + 400 + 600 + 300 + 600 = 2,000 square feet
