Answer:54sqft
Step-by-step explanation:
A=b*h/2
A=9*12/2=54sqft
So hmm notice the picture below
thus

so, is clearly not 0, so it has to be 1.74
An equation to solve for the time when the high school will have exactly 100 students is (1-.06)^x = (250/100).
That simplifies to 94^x = .4.
We can then take the log of both sides to isolate the x variable from the exponent. Here's with natural log.
x*ln(.94)=ln(.4)
x = ln(.4)/ln(.94)
Solving this gives x ~= 14.80. So in about 15 years, the high school will have 100 students.
