Answer:

104 cm², 88 cm²

Step-by-step explanation:

∴ Area of figure(I) = Area of trapezium = (1/2)[a + b) * h

                                                               = (1/2)[30 + 22] * 4

                                                               = (1/2)[52] * 4

                                                               = 104 cm².


Also, Area of figure(II) = 104 cm².

∴ Area of figure(III) = Area of trapezium = (1/2)[a + b)] * h

                                                                 = (1/2)[26 + 18] * 4

                                                                 = (1/2) * 44 * 4

                                                                 = 88 cm²


Also, Area of figure IV = 88 cm².


Therefore:

Area of figure I = Area of figure II = 104 cm².

Area of figure III = Area of figure IV = 88 cm².


Hope it helps!

Step-by-step explanation:

Area of figure(I) = (1/2)[a + b) * h

                           = (1/2)[30 + 22] * 4

                            = (1/2)[52] * 4

                            = 104 cm².

Area of figure(II) = 104 cm².

Area of figure(III) = (1/2)[a + b)] * h

                            = (1/2)[26 + 18] * 4

                            = (1/2) * 44 * 4

                            = 88 cm²

Area of figure IV = 88 cm².
