Answer 2

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.


Hope this helps!
