Answer 1

Answer:

area of isosceles triangle = 1/2 base x height

                                        =1/2  x 15 x 15

                                         =112.5

area of another isosceles triangle = 1/2 x 4 x 4

                                                    = 8

area of rectangle = 25 x 4 ( length x breadth)

                          =100

therefore the area of polygon is 100+112.5+8

                                                      220.5
