What is the area of the shaded region?

42.5 square.cm

Step-by-step explanation:

Find the diagram attached

Area of the shaded portion = area of square - area of circle

Area of square = L²

Area of square = 11 × 11

Area of square = 121 square centimetres

Area of circle = pir²

r is the radius of the circle = 5cm

Area of the circle = 3.14×5²

Area of the circle = 3.14×25

Area of the circle = 78.5 square. cm

Area of the shaded region = 121 - 78.5

Area of the shaded region = 42.5 square.cm
