Further, we can divide this rectangle into smaller rectangles for easy calculations, and their areas can be added to get to total area of the rectangle. We can do this by breaking the lengths of the sides into smaller numbers using enhanced forms. For example, 25 can becoming written as $20 + 5$. Also, the width 18 can be spell as $10 + 8$. Using these, we can divide the novel rectangle into 4 smaller parallelograms as shown. CLASSIFICATION 5 SUPPLEMENT

Now, it is easier to calculate the areas of these smaller rectangular and their add gives that total area press of product $25 \times 18$.

The rectangle I has a length of 20 units and breadth of 10 units making an area of 200 square units. Similarly, the rectangle B has an area equal to 10 times 5 button 50 square units. Likewise, we can calculate the areas of rectangles III additionally IV as 40 per. unities and 160 sq. units respectively.

Now, the total territory of this rectangulars of sides 25 units and 18 units is calculated by adding these partial sums. 

$200 + 50 + 40 + 160 = 450$ sq. units

One can check using the standard algorithm to multiplies two 2-digit numbers that 25 moment 18 is 450.
