Show Answer
Answer:
Correct Answer: C
Solution:
- Length of wire s Circumference of the circle with radius of 35 m Circumference of the circle $ =2\pi r $ $ =2\times \frac{22}{7}\times 35=220cm $ Let the length of rectangle be $ 6xcm. $ Then, its breadth is $ 5x. $
$ \therefore $ $ 2(6x+5x)=220 $
$ \Rightarrow $ $ 2(11x)=220 $
$ \Rightarrow $ $ 22x=220 $
$ \Rightarrow $ $ x=10 $
Smaller side of rectangle $ =5\times 10=50cm $
