Answer 2

Answer:

Sides=9,12,15 Area = 699.81

Step-by-step explanation:

Perimeter = Sum of all Sides

Let the Sides be 3x 4x and 5x

so, 3x+5x+4x=36

12x=36

x=36/12

x=3

So first side = 3*3=9

Second side =4*3=12

Third side =5*3=15

Area of a Triangle =

√s(s-a)(s-b)(s-c)

Here S = Sum of all sides

So, S=9+12+15=36

s-a= 36-9=27

s-b= 36-12=24

s-c= 36-15=21

Area = √36*27*21*24

Area=√489888

Area = 699.81
