" a triangle is "30" cand the circumicrence of in "

The perimeter of a triangle is 30 cm and its area is 30 cm^(2) . If the largest side measures 13 cm, what is the lengh of the smallest side of the triangle ?

Calculate the area and perimeter of a triangle of sides 30 centimetre, 28 centimetre and 30 centimetre. Also calculate the radius of the incircle.

If triangle ABC is similar to triangle PQR , Perimeter of triangle ABC = 30 cm , Perimeter of triangle = 45 cm , PR = 9 cm then find AC.
