Question

Lights off three sides of a triangle are 1 is to 3 is to 5 and perimeter of the triangle is 270 find the sides

Answer 1

Answer:

let the sides are x unit,3x unit and 5x unit

so perimeter =(x+3x+5x)=270

=> 9x=270

=> x=270/9

=> x=30

so the sides of the triangle are 30 unit, 3×30unit=90unit and 5×30 unit=150 unit
