Q. 8

# A paper is in the form of a rectangle ABCD in which AB = 20 cm and BC = 14 cm. A semicircular portion with BC as diameter is cut off. Find the area of the remaining part.

Answer :

The figure is given below:

Diameter of semi-circle = BC = 14cm

Radius of semi–circle

= 7cm

Area of semi-circle

= 77 cm^{2}

Area of sheet = 20 × 14 = 280 cm^{2}

Thus, Area of remaining sheet = 280-77

= 203 cm^{2}
