side of triangle = 5x +3x+3x
=11x = 110
x =110/11
x = 10
side of triangle are
50 ,30,30
area by herons formula
s =110 /2
s=55
=11x = 110
x =110/11
x = 10
side of triangle are
50 ,30,30
area by herons formula
s =110 /2
s=55

Answer:
414.578 square cm.
Step-by-step explanation:
We are given that sides of triangle are in the ratio 5:3:3
Let the ratio be x .
So, Sides will be 5x ,3x,3x
Since we are given that the perimeter of the triangle =110 cm
Perimeter of triangle = Sum of all side
So, 110= 5x+3x+3x
110 = 11x
So, x = 10
So, sides : a= 5*10 = 50 cm
b = 3*10 = 30 cm
c = 3*10 = 30 cm.
Now to find the area of triangle we will use heron's formula.
Where
a,b,c are the side lengths of triangle
Now substitute the values :
Hence the area of the triangle is 414.578 square cm.
