Answer 2

Answer:

radius of circle = 20cm

Step-by-step explanation:

area = area of 3/4th part of circle + area of

reactangle

= 3/4×πr² + l×b

= 3/4×22/7×(20)² + 50×40

= 3/4×22/7×400 + 2000

=26400/28 +2000

= 2942.85 ≈ 2942cm²

and, perimeter = 3/4th of circle + perimeter of

rectangle

= 3/4×2πr + 2×(50+40)

= 3/4×2×22/7×20 + 180

= 234.2cm answer
