Question

Ratio of three sides of a triangle are 1 : 3 : 5 and perimeter of the triangle is 270m. Find

the sides.​

Answer 1

let the three sides of a triangle be 1x,3x ,5x

perimeter of a triangle

=a+b+c=270

=1x+3x+5x=270

=9x=270

x=30

therefore, sides of the triangle

1x=30 m

3x=3×30=90m

5x=5×30=150m

I hope this helps ( ╹▽╹ )

Answer 2

$let \: the \: 3 \: sides \: be: \\ 1n(first) \\ 3n(second) \\ 5n(third) \\ \\ (as \: we \: know) : \\ \\ perimeter \: of \: a \: triangle \: = \\ (sum \: of \: the \: 3 \: sides)units \\ now : \ \\ 270 = 1n + 3n + 5n \\ 270 = 9n \\ \frac{270}{9} = n \\ 30m \: \: \: = n \: \\ \\ \\ so \: the \: first \: side \: = 30m \\ second \: side \: \ \: \: \: \: \: \: \: \: = 90m \\ third \: side \: \: \: \: \: \: \: \: \: \: \: \: \: = 150m \\ \\ \\ \\ hope \: it \: helps \: you...$
