Question

a sides of triangle are in ratio 2:3:4and perimeter is 18.thevarea of the triangle​

Answer 1

Answer:

let the sides be 2x, 3x and 4x

perimeter = sum of all sides

18= 2x +3x+4x

or 9x=18

or ×=2

sides are : 4, 6, 8

(using herons formula)

area of a triangle = root (s(s-a)(s-b)(s-c))

= root( 18×14×12×10)

= root(3×3×2×2×7×2×3×2×2×5)

= 12(root150)

ig this is the area
