Question

the side of a triangle are in the ratios, 1:1.5:2 and it's perimeter is 18 cm. Find the length of each side​

Answer 1

given

sides of a triangle are in the ratios 1:1.5:2

perimeter is 18 cm

to find

length of each side

assumption

let the ratio be in terms of x

solution

sides of triangle are x, 1.5x, 2x

perimeter = x + 1.5x + 2x

= 4.5x

given perimeter = 18

therefore 4.5x = 18

===> x = 4

===> x = 41.5x = 6

2x = 9
