The perimeter of a right triangle is 12 cm. Its hypotenuse is 5 cm and base is 4 cm. Find the area of the triangle.​

Answer»

Answer:

the perimeter of a triangle = SUM of all sides of a triangle

12CM = a + 5 + 4

a = 12cm - [5cm+4cm]

a = 12cm - 9cm

a = 3cm

area = 1/2bh

          1/2*4cm*3cm

           6cm²
