answer this que................................10......?

Answer 1

area of remaining part =area of rectangle -2(area of semi circle)
=l*b-2(1/2pi r*r)
=70-22/7*12.25
=70-22*1.75
=70-38.5
=31.5cm*cm

Answer 2

AREA of remaining part = area of rectangle - area of 2 semi circles
= l × b - 2×1/2 pie ×r^2
10×7 - 2×1/2 ×22/7 ×7/2×7/2
70 - 1× 11 ×7/2
70-77/2
63/2
31.5
