Question

the longest side of a triangle id 26 m . Its perimeter is 55 m and its shortest side is half of its longest side . Find the length of its third side .

Answer 1

Answer:

length of third side = 16m

Step-by-step explanation:

perimeter of triangle = 55m

longest side = 26 m

shortest side = 26/2 = 13m

third side = x

perimeter = sum of all side

55 = 26 + 13 + x

55 = 39 + x

55 - 39 = x

16 m = x

Answer 2

Answer:

Step-by-step explanation:

Longest side=26m

So, shortest side=26/2=13m

Perimeter=55m

Let 3rd side be x

So,

26+13+x=55

39+x=55

x=55-39

x=16
