Question

if the sides of a triangle are in the ratio 8:4:6 and its perimeter is 72 cm, find the area of the triangle.
​

Answer 1

Answer:

hey mate here is your answer

perimeter of triangle=72

let side=8x+4x+6x

72=8x+4x+6x

72÷18=x

4=x

8×4=32

4×4=16

6×4=24

Answer 2

Answer:

let the length be :a,b,c

a= 8x

b=4x

c=6x

perimeter=72

a+b+c=72

8x +4x+6x= 72

18x=72

x=4

so, a= 32

b=16

c =24

and by using herons formula find area
