The total area of the window is 4.125 square feet.
To find the total area of the window, we need to find the areas of each section and add them together.
We can write an equation to model this problem:
total_area = section1_area + section2_area + section3_area
where:
total_area is the total area of the window
section1_area is the area of the first section of the window
section2_area is the area of the second section of the window
section3_area is the area of the third section of the window
We can then calculate the area of each section by multiplying its width and height.
section1_area = section1_width * section1_height
section2_area = section2_width * section2_height
section3_area = section3_width * section3_height
Plugging these values into the original equation, we get:
total_area = (section1_width * section1_height) + (section2_width * section2_height) + (section3_width * section3_height)
total_area = (1.8 ft * 1.25 ft) + (1.5 ft * 0.75 ft) + (1.5 ft * 0.5 ft)
total_area = 2.25 ft² + 1.125 ft² + 0.75 ft²
total_area = 4.125 ft²
Therefore, the total area of the window is 4.125 square feet.
