Question

the area of a triangle is 72 cm square and the three altitudes measures 24 cm, 18 cm, and 16 cm. find the perimeter of the triangle.

Answer 1

Answer:

23cm

Step-by-step explanation:

let the triangle be ABC with altitudes AF,BE, and CD on BC,AC and AB respectively.

then area = 1/2 x base x height

          72      = 1/2 x AC x 18

                 AC = 8 cm

similarly BC = 6 cm

              AB = 9cm

so perimeter = 8 + 9 + 6  = 23cm

Answer 2

Answer:

23 cm is the answer
