Answer 1

Answer:

The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.

Step-by-step explanation:

2(L+B)

Answer 2

Given:

A rectangle

To Find:

The formula of the perimeter of a rectangle.

Solution:

The perimeter of any shape is the sum of the lengths of all it's sides.

A rectangle has 4 sides of which two of it's sides are length and two of it's sides are breadth.

The two length sides are equal and the two breadth sides are equal.

Perimeter P = l + l + b + b

P = 2l + 2b

P = 2(l+b)

The formula of the perimeter of a rectangle is 2(l+b).
