Answer 2

Answer:

252cm

Step-by-step explanation:

area of circle and rectangle = 2261cm²

diameter of the circle= 42 cm

length of the rectangle= 25 cm

diameter of circle=42cm

radius of circle= 42/2= 21

sum of area of rectangle and circle=

πr² + lb= 2261cm²

breadth=

= 22/7×21²+ lb = 2261

= 1386+ 25b=2261

=25b=2261-1386

=25b=875

=b=35

circumference of circle= 2πr=132cm

perimeter of rectangle=2×(l+b)= 120cm

sum of circumference and perimeter=132+120=252cm
