In the given figure, a circle is inscribed in a trapezium of height 14 cm and lengths of parallel sides are equal to 25 cm and 40 cm. What is the area of the shaded region?
301 sq.cm
Area of the shaded region
= Area of the trapezium - Area of the circle
Area of trapezium
= 12×height×sum of parallel sides
=12×14×(25+40)=455 sq.cm
Area of the circle =π×r2=227×7×7=154 sq.cm
Hence, area of the shaded region =455−154
=301 sq.cm.
