Question

The length of a rectangle is 3 times its width. The perimeter of the rectangle is 48 cm.

Answer 1

Answer :-

• Breadth = 6cm
• Length = 18cm

Given :-

• The length of a rectangle is 3 times its width. The perimeter of the rectangle is 48 cm.

To Find :-

• Length and breadth of the rectangle.

Solution :-

Let

• The width of the rectangle be x.
• The length of the rectangle will be 3x.

→ It's given that the perimeter of the rectangle is 48cm.

As we know that

Perimeter of a rectangle is 2 (l + b)

Where,

• l = length
• b = breadth

According to question :-

2 (3x + x) = 48

→ 2 × 4x = 48

→ 8x = 48

→ x = 48/8

→ x = 6

Hence

• Breadth of the rectangle = x = 6cm
• Length of the rectangle = 3x = 3×6 = 18cm
