Question

Find the perimeter of a rectangle whose Length=20cm,breadth=10cm

Answer 1

Answer:

$perimeter = 2(20 + 10) \\ = 2 \times 30 = 60cm$

Answer 2

Given - Length : 20 cm

Breadth : 10 cm

Find - Perimeter of rectangle.

Solution - Rectangle has adjacent sides of same length. The formula for perimeter of rectangle is 2*(l + b). In the mentioned formula, l represents length and b represents breadth.

Now, as we have values of length and breadth, keeping them in given formula to find perimeter of rectangle.

Perimeter = 2*(20 + 10)

Perimeter = 2*30

Perimeter = 60 centimetres

Therefore, perimeter of rectangle is 60 centimetres.
