Expert Answer
Given that :-
Length of the rectangle = 5.6 cm
Breadth of the rectangle = 3.9 cm
We know that :-
Area of the rectangle = length x breadth
= 5.6 x 3.9
Multiply as you would multiply whole numbers
= 56 x 39
= 2184
Count the number of decimal places. There is 1 decimal place in 5.6 and 1 decimal place in 3.9. So, move the decimal point 2 places to the left in the answer.
2184. → 21.84
Thus,area of the rectangle is 21.84 cm2
