Question

The formula to find perimeter of a rectangle = l x l​

Answer 1

Answer:

Perimeter of rectangle =2(l+b)

Step-by-step explanation:

Perimeter of the rectangle =2(l+b)

let's take a rectangle Abcd to find perimeter

Perimeter of rectangle = AB+BC+CD+DA

We know that opposite sides of rectangle are equal.

Perimeter of rectangle = AB+BC+AB+BC

Perimeter of rectangle = 2AB+2BC

Perimeter of rectangle = 2(AB+BC)

Since AB is length (l) and BC is breadth(b)

Therefore Perimeter of rectangle = 2(l+b)
