Question

perimeter of a triangle 2 is to 3 is to 5 and its perimeter 120 find the area of a triangle​

Answer 1

Answer:

Explanation here ratio is 2:3:5 and perimeter is 120

Area=?

Let the comman ratio be 2x ,3xand 5x..

A/q. 2x+3x+5x= 120

10x = 120

x= 12

Then the sides are 24 ,36 ,60

And this type of traingle is not possible because sum of two sidesis always greater than third side but here 24+36=60 . So the area is 0

Answer 2

Answer:

let no the no be 2x, 3x & 5x

p of triangle is s + s + s

120=2x + 3x + 5x

120=10x

120÷10=x

12=x

put the value = 2x= 2× 12=24

=3x=3×12=36

=4x=4×12=48
