Area of shaded region= 55-7.5= 47.5

Answer 2

The area of the shaded region = 47.5 cm²

Step-by-step explanation:

• To calculate the  area of the shaded region

         = Area of a rectangle - Area of a triangle.

• Area of rectangle= length x breadth.

                                     =  5 cm x  11 cm

                                     =   55 cm² .

• Area of triangle= 1/2 x base x height.

                                 =  1/2 x 5cm x 3cm.

                                 =  7.5 cm²

Area of shaded region = 55cm² - 7.5cm²

                                       =     47.5 cm²
