Question 146
The area of a rectangle is equal to the area of a circle with circumference equal to 220 m What is the length of the rectangle of its breadth is 50 m ?
Solution
Ciircumference = 2*(22/7)*r = 220
Hence, r = 35
Now, area of circle = (22/7)*35*35 = 3850
Area of rectangle is same as that of circle
Area of rectangle = 3850
Length * breadth = 3850
length = 3850/50 = 77m
Therefore, option C is correct answer.
