The blanket's area is 40,500 cm²
Further Explanation
The blanket length is 2.25 m
width is 1.8 m
The blanket usually in rectangular shape, so to calculate the area of the blanket would be:
[tex]\boxed {AREA = length \times width }\\ \boxed {=2.25 \times1.8 }\\ \boxed {=4.05 }[/tex]
so the blanket's area is 4.05 m²
Here is how to do decimal numbers multiplication:
2.25 ⇒ 2 decimal place
1.8 x ⇒ 1 decimal place
1800
235 +
4.050 ⇒ 3 decimal place
to multiply decimal numbers, it is the same process as multiply the whole numbers, except the decimal place position. In the calculation above:
the first factor has 2 decimal place
the second factor has 1 decimal place
so the result will have 3 decimal place (2+1)
Back to the question, after we find out the blanket's area in meters, let's convert it to centimeters
[tex]\boxed {1 m = 100 cm }\\ \boxed {(1m)^{2} = (100cm) ^{2} }\\ \boxed {1m^{2} = 10000 cm^{2} }[/tex]
so [tex]\boxed {4.05m^{2} = 4.05 \times 10000 cm^{2} }\\ \boxed {=40500cm^{2} }[/tex]
The blanket's area is 40,500 cm²
