Question

if the perimeter of triangle POR is 40cm and the rational of its sids are 1:3:4. find the side of tria​ngle

Answer 1

Step-by-step explanation:

let it be x .

then ; 1x+4x+3x= 40

8x = 40

x= 40÷8=5

Answer 2

Answer:

Given-POR is a triangle & it's perimeter is 40cm.

And rational of side is 1:3:4

Let's 1st angle is = 1x

2nd angle is =3x

& 3rd angle =4x

So,

1x + 3x + 4x = 40 cm.

8x=40cm

x=40/8 cm

x=5 cm

Hence,

1st side = 1x = 1 * 5 = 5 cm

2nd side= 3x = 3*5 = 15 cm

3rd side=4x = 4*5= 20 cm
