Answer 2

Given:

Perimeter = 8 cm

Length - Breadth = 0.8 cm

To find:

Length

Solution:

By formula,

Perimeter = 2 ( Length + Breadth )

2 ( Length + Breadth ) = 8

Length + Breadth = 4

Length - Breadth = 0.8

Equation and solving for Length,

2 Length = 4.8 cm

Hence, Length = 2.4 cm

The answer is ( 3 ) 2.4 cm
