Area of a Rectangle Formula

We have 4 × 3 = 12. The area of a rectangle is obtained by multiplying its length and width. Thus, the formula for the area, 'A' of a rectangle whose length and width are 'l' and 'w' respectively is the product "l × w".

Step-by-step explanation:

To find the area, first, find the length and width. The formula to find the area of a rectangle is A = l × w. Substitute 15 for 'l' and 4 for 'w' in this formula. Area of a rectangle = 15 × 4 = 60.
