Question

Using the lattice multiplication method, find the value of A.

$11\times 13=A$

• A. A = 132
• B. A = 165
• C. A = 154
• D. A = 143

Answer 1

The correct option is D A = 143

$\text{We have to find value of}11\times 13.$

Step 1: Let's make a table.


Step 2: We extend the diagonals and write the numbers.


Step 3: Now, we multiply the digits in the corresponding rows and columns.


Step 4: At last, we add all the digits diagonally and write the digits from left to right.


∴ The value of A = 143.
