Question

The sides of a triangle are in the ratios, 1:1.5: 2 and its perimeter is18 cm. Find the length of each side.​

Answer 1

Answer:

• Let the sides of a triangle= 1x ,1.5x and 2x

Given: the perimeter of triangle =18cm

Sum of all sides. = 18cm

1x+1.5x+2x. =18cm

4.5x. = 18cm

x. = 18 ×10/45

x. = 180/45

x. = 6cm

1. The lenght of first side = 1x =1(6) = 6cm
2. The length of second side =1.5x =1.5(6) = 9.0cm = 9cm
3. the length of third side = 2x= 2(6) = 12cm
