If `triangle` is the area and 2s is the perimeter of `triangleABC`, then prove that `triangle le s^(2)/(3sqrt(3))`

If A is the area and 2s is the sum of the sides of a triangle, then

If A is the area and 2s the sum of the sides of a triangle,then

If A is the area and 2s is the sum of the sides of a triangle,then A<=(s^(2))/(4) (b) A<=(s^(2))/(3sqrt(3))2R sin A sin B sin C( d) none of these

Given the perimeter of a triangle, prove that the triangle of the greatest area is equilateral.

The sides of a triangle are in the ratio 2:3:4. The perimeter of the triangle is 18 cm. The area (in cm^2 ) of the triangle is

The sides of a triangle are in the ratio 2:3:4 . The perimeter of the triangle is 18 cm. The area (in cm^(2) ) of the triangle is

Find the perimeter of an equilateral triangle whose are is 4sqrt3 cm^2 .

In an equilateral triangle with side a, prove that area =(sqrt(3))/(4)a^(2)
