Question

In a triangle the longest side is double the shortest side and the third side is 5 cm less than the longst side .if the perimeter of the triangle is 63 cm then find the length of all the side of the triangle

Answer 1

Answer:

Step-by-step explanation:

let the shortest side be =  x

then longest side = 2x

and the third side will be = 2x - 5

given perimeter = 63 cm

=> x + 2x + 2x - 5 = 63

=> 5x - 5 = 63

=> 5x = 63 + 5 = 68

=> x = 68 / 5 = 13.6 cm

shortest side  = x = 13.6 cm

longest side = 2x = 2 * 13.6 = 27.2

third side = 2x - 5 = 27.2 - 5 = 22.2
