Step-by-step explanation:
Since we have given that
Koda is solving
[tex]13\times 16[/tex]
According to question, he used an area model to help work through each step.
So, it can be written as
[tex]13=10+3\\\\16=10+6[/tex]
so, Let the length will be
[tex]13=10+3[/tex]
Let the breadth will be
[tex]16=10+6[/tex]
So, area will be
[tex]l\times b\\\\=(10+3)\times (10+6)\\\\=10(10+6)+3(10+6)\\\\=10\times 10+10\times 6+3\times 10+3\times 6\\\\=100+60+30+18\\\\=208[/tex]
So,
13×16=208
Solution:
13 × 16= 16 × 13, as multiplication of numbers follow commutative property→ [ Area model]
→→→ Draw 13 squares in 16 rows
or
Draw 16 squares in 13 rows
or
Draw 13 squares in 16 columns
or
Draw 16 squares in 13 columns
or
Draw square of side 16 units or any square of side ≥ 16 cm and cut rectangle of dimensions 13 × 16 or 16 × 13.
In all the cases count the number of squares to get the product of 13 × 16= 16 × 13 which is equal to 208 square units.
