Answer:
136
Step-by-step explanation:
To get the percent, divide 27 by 150 then multiply the quotient by 100.
(27 / 150) * 100 = 18%
For this case, the first thing we should do is use the following equation:
x ^ 2 + x-30
Here, we substitute the value of x = 20
We have then:
(20) ^ 2 + (20) -30 = 390 m ^ 2
Answer:
the area of the land when the length of the dentist's office is 20 meters is:
390 m ^ 2
