Final Answer:
The error in the program is on line 4, where the multiplication operator () is missing between the variables length and width. The correct expression should be area = length width. Adding the multiplication operator will fix the program and produce accurate results.
Step-by-step explanation:
The error in the program occurs on line 4, where the calculation for the area of the rectangle is incorrect. The original expression “area = length width” is missing the multiplication operator (), which results in an incorrect calculation. By adding the multiplication operator, the correct expression should be “area = length width”. This change will ensure that the program accurately calculates the area of the rectangle.
The multiplication operator (*) is essential in programming to perform arithmetic operations. In this case, without it, the program simply assigns the value of “length” to “area” and then multiplies it by “width”, which leads to an incorrect result. By fixing this error, the program will accurately calculate the area of a rectangle by multiplying its length and width.
In summary, by adding the missing multiplication operator (*) between “length” and “width” on line 4 of the program, we can rectify the error and ensure that accurate results are obtained when calculating the area of a rectangle.
