Final answer:
To find the total area of the two rectangles, add the areas of each rectangle. The expression for the total area is l1 * w1 + l2 * w2.
Step-by-step explanation:
To find the total area of the two rectangles, you need to add the areas of each rectangle. Let's say the length and width of the first rectangle are 'l1' and 'w1' respectively, and the length and width of the second rectangle are 'l2' and 'w2' respectively. The expression for the total area would be:
Total area = l1 * w1 + l2 * w2
To evaluate the expression, substitute the values for the lengths and widths of the rectangles and multiply accordingly. For example, if l1 = 4, w1 = 5, l2 = 6, and w2 = 3, the calculation would be:
Total area = 4 * 5 + 6 * 3 = 20 + 18 = 38
