Question

Sides of traingle is 2:3:4.The perimeter 18 cm area of triangle

Answer 1

Perimeter = a+b+c = 18 cm²

first side = 2x

Second side = 3x

Third side = 4x

2x + 3x + 4x = 18

9x = 18

x = 18/9 = 2

first side = 2x = 2*2 = 4

Second side = 3x = 3*2 = 6

Third Side = 4*2 = 8

Area = √s(s-a)(s-b)(s-c) S = perimeter/2 =18/2 = 9

=√9(9-4)(9-6)(9-8)

=√9*5*3*1

=3√15 cm²
