Answer 2

Answer:

225

Step-by-step explanation:

Given that Area of a window = 3.78m 

                                                = 37800cm^2.

Given that two parallel sides = 17cm and 25cm, height = 8cm

We know that Area of trapezium = 1/2 * sum of parallel sides * height

                                                        = 1/2(17 + 25) * 8

                                                         = 42 * 4

                                                         = 168cm^2

Hence the number of trapeziums in the grill pattern = 37800/168

                                                                                       = 225

Therefore the total number of trapeziums = 225
