Answer:

area=600 cm²

perimeter=120 cm

Step-by-step explanation:

i) the perimeter of the triangle given is = (sum of all the sides of the triangle)

= 50 cm + 30 cm + 40 cm

= 120 cm is the perimeter of the triangle.

ii) the semiperimeter of the triangle is =

perimeter/2

= 120 cm/2

= 60 cm = s

therfore, area of a scalene triangle is =

√[s(s-side 1)(s- side 2)(s- side 3)]

√[60 * (60 - 50) * (60-40) * (60-30)]cm⁴

√(60 * 10 * 20 * 30)cm⁴

(10 * 10 * 2 * 3)cm²

600 cm² is the area of the triangle
