3x + 5x +7x = 300

15x = 300

x = 300/15

x = 20cm

sides of triangle are 3x = 3 × 20 => 60cm,

5x = 5 × 20 => 100cm and

7x = 7 × 20 => 140cm

QUESTION

Side of triangle are in the ratio 3:5 :7 and its perimeter is300cm.

in other word you have to find sides of traingle.

ANSWER

Given,

ratio of ∆=3:5:7

perimeter=300cm

let the sides of ∆ be x

then,sides of traingle will be 3x,5x,7x

now,

perimeter of traingle=sum of all sides

300cm=15x

300cm/15=x

20cm=x

here u have x=20cm

now sides of traingle will be 3×20cm=60cm,5×20cm=100cm,7×20cm=140cm

Hence, Sides of traingle are 60cm,100cm,140cm
