Answer:
The fabric needed for each pyramid cell of the kite will have an area of 173 cm².
Step-by-step explanation:
Area of a face of the triangular pyramids = (1/2)(b)(h)
where
b = base of a triangle of the triangular pyramid = 20 cm
h = height of each triangle of the triangular pyramids = 17.3 cm
Area = (1/2)(20)(17.3) = 173 cm²
Just like the image presented with the question, each face of the pyramid that has a cell of fabric has only one, So, the fabric needed for each pyramid cell of the kite will have an area of 173 cm².
Hope this Helps!!!
