Question

find the area of a triangular plot of sides are in the ratio of 4 : 5 : 6 and it's perimeter is 150cm​

Answer 1

Step-by-step explanation:

4x+5x+6x = 150

15x = 150

x = 10

sides are 40,50,60

s = 150/2 = 75

∆ = √(s(s-a)(s-b)(s-c)

∆ = √75(75-40)(75-50)(75-60)

∆= √(75)(35)(25)(15)

∆ = √984375

∆ = 992.16
