The area of the actual square window = 2.25 m².
<h3>Scale Drawing</h3>
Scale drawing relates the actual length of an object to its length on a paper.
Given a scale of 1 in = 2 m, it means 1 in on paper is about 2 m of the actual length of the object.
Thus:
- Length on scale drawing = 0.75 in
- Actual length = x
Therefore:
1/2 = 0.75/x
x = 1.5 m
Area of the actual square window = 1.5² = 2.25 m².

Answer:
y=3/4x-9
Step-by-step explanation:
1. Divide wire b in parts x and b-x.
2. Bend the b-x piece to form a triangle with side (b-x)/3
There are many ways to find the area of the equilateral triangle. One is by the formula A=

A=

Another way is apply the formula A=1/2*base*altitude,
where the altitude can be found by applying the pythagorean theorem on the triangle with hypothenuse (b-x)/3 and side (b-x)/6
3. Let x be the circumference of the circle.

so

Area of circle =

4. Let f(x)=

be the function of the sum of the areas of the triangle and circle.
5. f(x) is a minimum means f'(x)=0
f'(x)=

=0



6. So one part is

and the other part is b-
The formula for perimeter is 2(Length) + 2(width)
Fill in the known information:
22 = 2(6.5)+ 2(width)
Simplify:
22 = 13 + 2(width)
Subtract 13 from both sides:
9 = 2(width)
Divide both sides by 2:
Width = 4.5m
