The length of a rectangle is 5 m, and the breadth is 4 m. The perimeter of the rectangle in centimetres is ____.

Given,

The length of the rectangle (l) = 5 m (we know that 1m = 100 cm)

                                    = 5 × 100 cm = 500 cm

The breadth of the rectangle (b) = 4 m = 4 × 100 cm = 400 cm

The Perimeter of a rectangle = 2(l+b) = 2(500 + 400) = 2 × 900 cm = 1800 cm

Therefore, the perimeter of a rectangle is 1800 cm
