Answer:
<h2>5 cm</h2>
Step-by-step explanation:
The triangles are similar. Therefore the corresponding sides are in proportion:
<em>cross multiply</em>

<em>divide both sides by 32</em>

Because the function f(x) =-2+√x+7 has √x, x should be more or equal 0.
Domain is x≥0, or [0,+∞).
The smallest value of x=0, so the smallest value of f(x) is f(0) =-2+√0+7=5,
so range is f(x)≥5, or [5, +∞).
The perimeter of the room will be

<h3>Area of a square</h3>
A square is quadrilateral with 4 sides. The formula for calculating the area of the shape is given as:
A = L²
Given the following parameters
A = 
Substitute
L²

Determine the perimeter
Perimeter = 4L
Perimeter = 4(14x^6y^5z^3)
Perimeter = 
Hence the perimeter of the room will be
feet
