Answer 1

Answer:

══════ •『 ♡』• ════════════ •『 ♡』• ══════

25x + 14 x + 12 x = 510

51 x = 510

x = 510 ÷51

x = 10

25x= 25 ×10

= 250 m

14 x = 14 ×10

=140m

12x= 12 ×10

x= 120

so 250 m is the longest side

Explanation:

●▬▬▬▬๑۩۩๑▬▬▬▬▬●

Let the sides of the triangle be 12x cm , 14x cm and 25x cm Thus, we have Perimeter = 12x +14x + 25x = 25.5 = 51x x = 25.5/51 = 0.5 Greatest side of the triangle = 25x = 25 x 0.5 = 12.5 cm.
