I do this a little differently then most.....but if it varies directly, then I make a proportion......and f(x) is the same as y

3/12 = y/40
cross multiply
(12)(y) = (3)(40)
12y = 120
y = 120/12
y = 10 <===== so f(x) or y = 10

Answer:

6084 $\text{ft}^2$ .

Step-by-step explanation:

Please find the attachment.

We have been given that the home-office of Tri-star industries is made up of three square buildings, one for each department, with a triangular atrium in the middle. The area of the Plumbing building is 5,184 $\text{ft}^2$ and the area of the A/C building is 900 $\text{ft}^2$ .

We know that area of square is square of its side length. Since all building are squares, so to find the area of electrical building, we will use Pythagoras theorem.

$a^2+b^2=c^2$
