Answer 2

Given :-

• Perimeter of Classroom = 54m
• Breadth of Classroom = 8m

To Find :-

• Length of the Classroom.

Solution :-

❏ As we know that, Perimeter of Rectangle is given by [ Perimeter of Rectangle = 2 ( Length + Breadth ) ]

Putting the Values :

⟾ Perimeter of Classroom = 2 ( L + B )

⟾⠀⠀⠀⠀⠀⠀⠀ 54 = 2 ( Length + 8 )

⟾⠀⠀⠀⠀⠀⠀⠀ 54 / 2 = Length + 8

⟾⠀⠀⠀⠀⠀⠀⠀ 27 = Length + 8

⟾⠀⠀⠀⠀⠀⠀⠀ 27 - 8 = Length

⟾⠀⠀⠀⠀⠀⠀⠀ 19m = Length

________________

Verification :

➟ Perimeter of Classroom = 2 ( L + B )

➟ Perimeter of Classroom = 2 ( 19 + 8 )

➟ Perimeter of Classroom = 2 × 27

➟ 54 = 54

Hence Verified

Thus, Length of Classroom = 19m
