The blanket area is 40,500 cm²

The blanket measurement is

length = 2.25 m

width = 1.8

AREA = length x width

          =  

To multiply the decimal numbers, we are going to multiply them as the whole numbers

2.25           ⇒ 2 decimal place

   1.8  x      ⇒  1 decimal place

1800

225    +

4.050          ⇒ 3 decimal place

So, we get the area of the blanket is 4.050 m². The next step is to convert the unit from meter square to centimetres square

so

The blanket's area is 40500 cm²
