An equilateral triangle, a square and a circle have equal perimeter. If T, S and C denote the area of the triangle, area of the square and area of the circle respectively, then which one of the following is correct ?
Elementary MathematicsMensuration
- AT < S < C
- BS < T < C
- CC < S < T
- DT < C < S
Explanation
For a fixed perimeter, the circle encloses the greatest area, and a square encloses more than an equilateral triangle. So T < S < C. Hence option A.
