The length of a rectangle is three-fifth of the radius of a circle. The radius of the circle is equal to the side of a square, whose area is 6400 m2. The perimeter (in m) of the rectangle, if the breadth is 15 m, is:
  • a)
    160
  • b)
    120
  • c)
    126
  • d)
    180
Correct answer is option 'C'. Can you explain this answer?

The length of a rectangle is three-fifth of the radius of a circle. Th...
Given:
Length of rectangle = 3/5 of radius of circle
Radius of circle = Side of square with area 6400 m
2
Breadth of rectangle = 15 m 
Formulas used:
Area of square = (Side)2
Perimeter of rectangle = 2(Length + Breadth) 
Calculation:
Area of
square
= 6400 m
2
⇒ Side2 = 6400 
⇒ Side = √6400 = 80 m 
Radius of cirlce = Side of square = 80 m 
⇒ Length of rectangle = 3/5 × 80 = 48 m 
∴ Perimeter of the rectangle = 2(48 + 15) m 
⇒ 126 m

Given information:
- Radius of the circle = side of the square = √(6400) = 80 m
- Length of the rectangle = 3/5 * 80 = 48 m
- Breadth of the rectangle = 15 m

Calculating perimeter of the rectangle:
- Perimeter of a rectangle = 2*(length + breadth)
- Perimeter = 2*(48 + 15)
- Perimeter = 2*63
- Perimeter = 126 m
Therefore, the perimeter of the rectangle, when the breadth is 15 m, is 126 m. Hence, the correct answer is option 'C'.
