Answer 2

Correct Question:

• The length of a rectangular hallway is 3 times its breadth. If the perimeter of the hallway is 48 m. Find its length and breadth.

GivEn:

• The length of a rectangular hallway is 3 times its breadth.
• Perimeter of the hallway is 48 m.

To find:

• Length and Breadth of hallway?

Solution:

☯ Let Breadth of Rectangular hallway be x m.

Therefore, Length of rectangular hallway is 3x m.

Now,

According to the Question:

• Perimeter of rectangular hallway is 48 m.

We know that,

★ Perimeter of Rectangle = 2(l + b)

Therefore,

➯ 2(3x + x) = 48

➯ 3x + x = 48/2

➯ 3x + x = 24

➯ 4x = 24

➯ x = 24/4

➯ x = 6

Hence,

• Breadth of rectangular hallway, x = 6 m
• Length of Rectangular hallway, 3x = 3 × 6 = 18 m

⠀⠀⠀⠀⠀⠀⠀⠀More to know:

• Area of Rectangle = Length × Breadth

• Diagonal of Rectangle = √l² + b²

• Area of square = side × side

• Perimeter of square = 4 × side

• Diagonal of square = √2 × side
