Question

What is the perimeter of rectangle? ​

Answer 1

Step-by-step explanation:

PERIMETER OF RECTANGLE= 2×(LENGTH+BREADTH)

Answer 2

Answer:

2(l + b)

Step-by-step explanation:

We know that a rectangle has 4 sides.

We also know what the parallel sides of a rectangle are equal.

                         b

    ---------------------------------------

l    |                                            |    l

    |____________________|

                         b

The given figure shows a rectangle.

Let 1 set of parallel sides be 'l' and the other set be 'b'.

Perimeter = Sum of sides of the rectangle.

                = l + b + l + b

                = 2l + 2b

                = 2(l + b)
