When isabel began her book selling business, she stored her inventory in her garage. Now that her business has grown, she wants to rent a warehouse. The are of the warehouse is 8100 square feet. Her only requirement is it must be squared. write a function that expresses f(x)

x is the sidelength of the square;

f(x) = x^(2)

8100 = x^(2)

90 = x

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

2x^2+5x+17

your welcome. : )
