Answer:
Approximately -93.362
Step-by-step explanation:
Given:
Perimeter of the window = 18 inches
Length = 2.6 m
First, let's convert the length from meters to inches:
1 meter = 39.37 inches
Length in inches = 2.6 m * 39.37 inches/m ≈ 102.362 inches
Now, let's use the perimeter formula to find the width:
Perimeter = 2 * (Length + Width)
Substituting the given values:
18 inches = 2 * (102.362 inches + Width)
Simplifying the equation:
18 inches = 204.724 inches + 2 * Width
18 inches - 204.724 inches = 2 * Width
-186.724 inches = 2 * Width
Dividing both sides by 2:
-93.362 inches = Width
