Answer 2

Answer:

area of rectangular tin sheet = l x b

                                               = 100 x 80

                                               = 8000 sq. cm

area of cut four squares of side 10 cm = side x side

                                                               = 4 x 10 x 10

                                                               = 400 sq. cm

Area of the remaining sheet = area of rectangular tin sheet - area of cut four squares of side 10 cm

                                               = 8000 - 400

                                               = 7600 sq. cm
