1 answer:
The amount of plastic covering needed to cover the window is 25.71.
<h3>How much plastic covering is needed?</h3>The window consists of a semi circle and a rectangle. The circumference and the perimeter of the semi circle and a rectangle has to be determined.
Circumference of the semi circle = 1/2πd + d
Where:
π = 3.14
d = diameter = 3
1/2 x 3.14 x 3 + 3 = 7.71
Perimeter of the rectangle = 2(length + width)
2x (6 + 3) = 18
18 + 7.71 = 25.71
Please find attached an image of the window. To learn more about the perimeter of a rectangle, please check: brainly.com/question/3205029
