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
