Step-by-step explanation:

Steps involved in solving diagonal method:

Step 1: The given number contains two digits. So, draw a square and divide it into 4 sub squares as shown above. Write down the digits 6 and 7 vertically, as shown in above.

Step 2: Multiply each digit on the left of the square with each digit on the top, one by one. Write the product in the corresponding sub sequence. If the product is a two-digit number, write the tens digit above the diagonal and the units digit below the diagonal.

Step 3: Starting below the lowest diagonal, sum the digits diagonally. If the sum is a two-digit number, underline the unit digit and carry over the tens digit to the next diagonal.

Step 4: underline all the digits in the sum above the topmost diagonal.

Step 5: the underlined digits give the required square number.
