Question

it is a triangle has its side in ratio 2:3:5 semi perimeter 35 cm then what is the perimeter of triangle

Answer 1

70 is your answer

Let the sides are 2x, 3x and 5x

If semi perimeter =35

Then

The perimeter will be 2*35=70cm

Then

Perimeter =sum of all sides

Here, 70=2x+3x+5x

70=10x

70/10=x

7=x

Then the sides are:-

1)- 2*7=14cm

2)- 3*7=21cm

3)- 5*7=35cm

I hope this this will help you

_________ _________

Verification of the semi perimeter

(14+21+35)/2 should equal to 35

(35+35)/2 =35

70/2 =35

35 =35.

_______________

Hence proved that the sides are 14,21 and 35
