Answer:
104 inches
Step-by-step explanation:
No window dimensions are given. We might assume that the shape of the window can be defined by these coordinates:
(18,64), (28,40), (18,16), (8,40)
A graph of the points reveals the window to be a rhombus, so we can figure the length of one side to determine the lengths of all sides.
On edge of the window will have a length determined by the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
For (x1, y1) and (x2, y2) as (8, 40) and (18, 64), the edge length is ...
d = √((18 -8)^2 +(64 -40)^2) = √(10^2 +24^2) = √676
d = 26 . . . . . the length of one of the four edges
The total length of the four window edges is ...
4 × 26 = 104
104 inches of tape are needed.
