Area of Outer rectangle with length 34 cm and breadth 30 cm = Length x Breadth = 34 x 30 = 1020 cm²
Area of Inner rectangle with length 26 cm and breadth 22 cm = Length x Breadth = 26 x 22 = 572 cm²
Area of Isosceles trapezium with Parallel sides 26 cm and 34 cm = 1/2 x (Sum of parallel sides) x Height
= 1/2 x (26 + 34) x 4 = 120 cm²
Area of shaded region = 1020 - 572 - 120 = 328 cm²
