Question

What will happen to perimeter of a rectangle if its length is doubled and breath remains the same

Answer 1

Answer:

Perimeter increase by 50%.

Step-by-step explanation:

Let L = 100 m and B = 100 m.

Perimeter = 2(100+100) = 400

Now new dimensions are.

L = 200 m, B = 100 m.

Perimeter = 2(200+100) = 600

Change in Perimeter = [600-400/400]*100 = 50%.
