step by step​

Answer 1

Answer:

answer is 24.5 cm

Step-by-step explanation:

hope you got the right answer

Answer 2

Answer:

Perimeter of rectangle = Perimeter of square

Circumference of circle = 154 cm

If radius = r , ∴  C = 2πr

Since radius = Side of square,

⇒ 2πs = 154cm  

⇒ s = 154/2π = 24.5cm

(taking  π = 22/7)

Perimeter = 4 × 24.5 cm = 98 cm

(perimeter of sq. = 4a )

Let breadth be = b

So, 2(l+b) = 98

⇒ l+b = 49cm ⇒ b = 49-10 = 39cm

∵ Area of rectangle = lb

⇒ Area = 10cm * 39cm = 390 cm
