<h3>
Further explanation</h3>
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
<u> 1.8 x</u> ⇒ 1 decimal place
1800
<u>225 +</u>
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
