${\huge{\underline{\underline{\sf{\blue{SOLUTION:-}}}}}}$

Question

⠀⠀⠀⠀⠀☆ An isosceles triangle each of the equal ⠀⠀⠀⠀⠀sides is 12cm and perimeter is 30cm the ⠀⠀⠀⠀⠀length of third side.

Answer

⠀⠀⠀⠀⠀ ☆ Third side = 6cm

Given

⠀⠀⠀⠀⠀☆ Two Sides = 12cm

⠀⠀⠀⠀⠀☆ Perimeter = 30 cm

To Calculate

⠀⠀⠀⠀⠀☆ Length of Third Side

Step by step explanation

Length of Two Sides = 12cm ( ${\sf{\red{Given}}}$ )

Let the length of Third side be X

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀Using Formula

${\boxed{\red{\tt{Perimeter= Sum\:of\:all\:sides }}}}$

1 Side = 12cm

2 Side = 12cm

3 Side = x

Perimeter = 30cm

Putting values,

Perimeter = 1 Side + 2 Side + 3 side

➛ 30cm = 12cm + 12cm + Xcm

➛ 30cm = 24cm + Xcm

➛ 30-24 = x

➛ 6 = x

${\boxed{\red{\tt{X = 6cm }}}}$

${\huge{\underline{\underline{\sf{\blue{Hence:-}}}}}}$

⠀⠀⠀⠀⠀☆ Third Side is 6cm

Answer

⠀⠀⠀⠀⠀ ☆ Third side = 6cm

Given

⠀⠀⠀⠀⠀☆ Perimeter = 30 cm

To Calculate

⠀⠀⠀⠀⠀☆ Length of Third Side

Step by step explanation

Length of Two Sides = 12cm ( {\sf{\red{Given}}}Given )

Let the length of Third side be X

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀Using Formula

{\boxed{\red{\tt{Perimeter= Sum\:of\:all\:sides }}}}

Perimeter=Sumofallsides

1 Side = 12cm

2 Side = 12cm

3 Side = x

Perimeter = 30cm

Putting values,

Perimeter = 1 Side + 2 Side + 3 side

➛ 30cm = 12cm + 12cm + Xcm

➛ 30cm = 24cm + Xcm

➛ 30-24 = x

➛ 6 = x

{\boxed{\red{\tt{X = 6cm }}}}

X=6cm
