Question

Tap on the correct option.
Using the lattice method of multiplication, find $2,200\times 15.$

• A. 33,000
• B. 31,000
• C. 32,000

Answer 1

The correct option is A 33,000

To find $2,200\times 15$ using lattice method of multiplication, we need $4\times 2$ rectangular table on which digits of $2,200$ and $15$ will be arranged as shown in below figure,

Now, multiplying digits on top with the digits on the right of the rectangle one by one

Plce the ones digits of their product on left and tens digit on right of the diagonal of respective smaller rectangle as shown in below figure,
Now, adding the digits along the diagonals as shown in below figure,
Finally taking the simplified digits from left to bottom in order will give the product as shown in below figure,
$\therefore$ $2,200\times 15=33,000$
