Find the third side of the triangles whose
(a) Two sides : 4 cm, 5 cm; Perimeter = 15 cm
(b) Two sides : 6 cm, 9 cm; Perimeter = 20 cm
(c) Two sides : 5 cm, 2 cm; Perimeter = 12 cm
(d) Two sides : 8 cm, 3 cm; Perimeter = 18 cm
(e) Two sides : 8 cm, 5 cm; Perimeter = 24 cm
(f) Two sides : 9 cm, 13 cm; Perimeter = 37 cm
S O L U T I O N :
As we know that Perimeter of a triangle is
\star \: \underline{ \boxed{ \frak{ \green{{ \sf P}erimeter_{(Triangle)} }= \red{{1}^{st} \: side} + \purple{ {2}^{nd} \: side }+ \pink{ {3}^{rd} \: side} }}}⋆
Perimeter
(Triangle)

st
side+2
nd
side+3

side
Here, in all the six cases we need to find the third side
Case (a)
Two sides : 4 cm, 5 cm; Perimeter = 15 cm
Perimeter = 4 cm + 5 cm + 3rd Side
15 cm = 9 cm + 3rd Side
3rd Side = 15 cm - 9 cm
3rd Side = 6 cm
Case (b)
Two sides : 6 cm, 9 cm; Perimeter = 20 cm
Perimeter = 6 cm + 9 cm + 3rd Side
20 cm = 15 cm + 3rd Side
3rd Side = 20 cm - 15 cm
3rd Side = 5 cm
Case (c)
Two sides : 5 cm, 2 cm; Perimeter = 12 cm
Perimeter = 5 cm + 2 cm + 3rd Side
12 cm = 7 cm + 3rd Side
3rd Side = 12 cm - 7 cm
3rd Side = 5 cm
Case (d)
Two sides : 8 cm, 3 cm; Perimeter = 18 cm
Perimeter = 8 cm + 3 cm + 3rd Side
18 cm = 11 cm + 3rd Side
3rd Side = 18 cm - 11 cm
3rd Side = 7 cm
Case (e)
Two sides : 8 cm, 5 cm; Perimeter = 24 cm
Perimeter = 8 cm + 5 cm + 3rd Side
24 cm = 13 cm + 3rd Side
3rd Side = 24 cm - 13 cm
3rd Side = 11 cm
Case (f)
Two sides : 9 cm, 13 cm; Perimeter = 37 cm
Perimeter = 9 cm + 13 cm + 3rd Side
37 cm = 24 cm + 3rd Side
3rd Side = 37 cm - 22 cm
3rd Side = 15 cm
