Step 1: Recall on how to find factors of the variables

Find the factors of all the variables in the grid

x^{2} = x\times x

7 x = 7\times x

8 x = 8\times x

56 = 7\times 8

Step 2 : Write these factors to the left and the top of the corresponding variable

Step 3: Write the equivalency statement

Length = x + 7

Width = x + 8

So area = (x+7) (x+8)
