Answer:
Breadth=16 cm
Length = 25cm
Area of Rectangular paper = l × b
= 25×16
= 400cm²
4 quadrant is cut from corner
Join 4 quadrant to form a complete circle
Readius = 7 cm
Area of circle = πr²
=22/7 × 7×7
= 22× 7
=154cm²
Area of remaining part = area of rectangle - area of circle
= (400-154)cm²
= 246cm²
