Answer:
Area model is one of a simple step to understand the given situation. So to make it simple, we need to decompose the number.
given number = 4.6 and 3
First we need to get the whole number and start multiplying:
Whole number of 4.6 => 4
whole number of 3 => 3
Now, let’s start multiplying the whole number
=> 4 x 3
=> 12
Then let’s multiply the remaining decimal:
=>.6 x 3
=> 1.8
Then add
=> 12 + 1.8
= 13.8
we know that
The area model for multiplication is a pictorial way of representing
multiplication. In the area model, the length and width of a rectangle
represent factors, and the area of the rectangle represents their product
So
in this problem
the factors are
l e n g t h 4.6 w i d e 3
decompose the number
4.6
4.6 = ( 4 + 0.6 ) A r e a o f r e c t an g l e = A r e a r e ct a n g l e 1 + A r e a re c t a n g l e 2 = ( 4 + 0.6 ) ∗ 3 = 4∗ 3 + 0.6 ∗ 3 = 12 + 1.8 = 13.8
see the attached figure to better understand the problem
therefore
the answer is
the product of
4.6
and
3
is equal to
13.8
