80 is 1 unit

So there is 6 units in total

80×6=480

But notice that 4 rectangle breadths = 1 rectangle length

So 80cm = 4 rectangle breadths + 1 rectane breadth

= 5 rectangle breadths

1 rectangle breadth = 80cm ÷ 5 = 16cm

Length of carpet (not rectangle, don't mix up the two)

= Length of 2 rectangles + breadth of 4 rectangles

= 2 x 64cm + 4 x 16cm

= 128cm + 64cm

= 192cm

Perimeter of carpet

= 2 lengths of carpet + 2 breadths of carpet

= 2 x 192cm + 2 x 80cm

= 384cm + 160cm

= 544cm

So final answer should be 480cm + 64cm = 544cm

Thank you :)

1L + 1B = 80cm

From the layout of the carpet, 4 breadths of the rectangle makes up 1 length of the rectangle.

1L = 4B

4B + 1B = 80cm

5B = 80cm

1B = 16cm

12B = Length of carpet.

12B = 16 x 12cm = 192cm

Total perimeter of carpet

= 192 + 192 + 80 + 80

= 544cm
