Question

The sides of a triangle are in the ratios, 1 15:2 and its perimeter is 18 cm. Find the length of each side​

Answer 1

Step-by-step explanation:

let the length be 1x,15x and 2x perimeter of triangle = sum of all sides

18cm = 1x + 15x + 2x

18 cm = 18 x

18cm / 18 = x

hence x = 1

first side = 1×1 =1

second side = 15 × 1= 15

third side = 2×1 = 2
