Explanation

The perimeter of an isosceles triangle-:

P = 2 ( Y ) + X

P= Perimeter

Y =Two Equal sides

X = Third side

_____________________________

Given,

The perimeter of an isosceles triangle =

18 cm

Length of two equal sides = 23/4

The perimeter of an isosceles triangle-:

P = 2 ( Y ) + X

P= Perimeter = 18 cm

Y =Two Equal sides = 23/4 cm

X = Third side = ??



Then ,

2 x (23/4) + x = 18 cm


= 23/2 + X = 18


= 23 + 2X = 36


= 2X = 36 - 23


= X = 13/2 cm.

Third side of isosceles triangle =

X = 13/2 cm.

Third of isosceles triangle = 13/2 cm
