Question

in a triangle, the longest side is double the shortest side and the third side is 3 cm less than the longest side . If the perimeter of the triangle is 57 cm , find all sides of the triangle​

Answer 1

Explanation:

Let shortest side be x

longest side = 2x

third side = 2x-3

A. T. Q.,

x+2x+(2x-3) =57

5x-3=57

5x= 57+3

5x=60

x=60/5

x=12cm

Thus,

Longest side is 24cm

shortest side is 12 cm

third side is 21cm
