Question

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

Answer 1

Given :

Ratio of the three sides = 1:3:5

Perimeter = 270 m

To find : All the sides

Solution: Let the ratio in the form of x

1x:3x:5x

Now ,

According to Question ,

1x+3x+5x = 270

9x = 270

x=270/9 = 30

Values of the ratio = 1x = 30m , 3x = 90m , 5x = 150m .

Answer 2

Ratio of three sides = 1:3:5
Let the sides be x, 3x and 5x

Perimeter of triangle = 270m

x+3x+5x = 270
9x = 270
x = 270/9
= 30

So,
First side = x = 30m
Second side = 3x = 3×30 = 90m
Third side = 5x = 5×30 = 150m
