Answer 2

Given :

• Length = 8cm
• Breadth = 12cm

To Find :

• Perimeter of rectangle

Solution :

We've, l = 8cm and b = 12 cm

By using formula,

$\tt \longrightarrow \: Perimeter \: of \: rectangle \: = \:2(l + b) \\ \\ \\ \tt \longrightarrow \: Perimeter \: of \: rectangle \: = \:2(8 + 12) \\ \\ \\ \tt \longrightarrow \: Perimeter \: of \: rectangle \: = \:2 \times20\\ \\ \\ \tt \longrightarrow \: Perimeter \: of \: rectangle \: = \:40cm$

•°• Hence, Perimeter of triangle = 40cm
