Answer:
95.72 m^2
Step-by-step explanation:
area of rectangle = 20*20
= 400 m^2
area of two semicircle of radius 20/2 = 10m = π r ^2
=22/7*10*10 = 314.28 m^2
area of remaining paper = area of rectangle - area of two semicircle
are of remaining paper = 400 . 00 - 314 . 28
- area of remaining paper = 95.72m^2
