" If "13,14,15" are the sides of a triangle,then the area of a triangle is square unit is "

IF 13,14,15 are the sides of the triangle , then the area of the triangle in sq. unit is

Let P, Q, R be the mid-points of sides AB, BC, CA respectively of a triangle ABC. If the area of the triangle ABC is 5 square units, then the area of the triangle PQR is

The sides of a triangle are 13,14,15, then the radius of its in-circle is

The sides of a triangle are 13,14,15, then the radius of its in-circle is

The perimeter of a right triangle is 12+8sqrt(3) . The sum of the square of all three sides is 294 sq.units.If the area of the triangle in square units is Delta then find (Delta^(2))/(12) .

If the sides of the triangle are 13,14,15 then the radius of the incircle is

The ratio of sides of a triangle is 3:4:5 . If area of the triangle is 72 square unit, then the length of the smallest side is :

The ratio of sides of a triangle is 3:4:5 and area of the triangle is 72 square unit. Then the area of an equilateral triangle whose perimeter is same as that of the previous triangle is

The ratio of length of each equal side and the third side of an isosceles triangle is 3:4. If the area of the triangle is 18sqrt(5) square units, the third side is
