The garden around the flat house is divided as follows: 30 percent flowers, 35 percent orchards, and 150 square meters from the lawn. What is the total area?

Correct answer:

x =  428.5714 m2

Step-by-step explanation:


30/100x + 35/100 x + 150 = x

30/100·x + 35/100·x + 150 = x

35x = 15000


x = 15000/35 = 428.57142857

x = 3000/7 ≈ 428.571429
