Question

From each corner of a rectangular paper (30 cm *20 cm) a quadrant of a circle of radius 7 cm is cut. Find the area of the remaining paper i. e shaded portion

Answer 1

4 quadrants make a circle of of radius 7 cm.
so area of circle = πr²
=22/7 * 7*7
=22*7
=154 cm²

Area of rectangle:-
=l*b
=30*20
=600 cm²

remaining area= area of rectangle- total area cut out
=600-154
=446 cm²
