Question

Why is the perimeter of a rectangle calculated as 2 × (length + breadth)?

पर्याय

• All four sides of a rectangle are equal

• Opposite sides of a rectangle are equal

• The diagonal divides the rectangle into two equal parts

• Length is always twice the breadth

Answer 1

Opposite sides of a rectangle are equal

Explanation:

In a rectangle, the two lengths are equal and the two breadths are equal.

Therefore, perimeter = length + breadth + length + breadth = 2(length + breadth).
