This is a C++ problem

#include  #include  using namespace std; // This program uses a structure to hold data about a rectangle // It calculates the area and perimeter of a box // PLACE YOUR NAME HERE // Fill in code to declare a structure named dimensions that // contains 2 float members, length and width // Fill in code to declare a structure named rectangle that contains // 3 members, area, perimeter, and sizes. area and perimeter should be // floats, whereas sizes should be a dimensions structure variable int main() { // Fill in code to define a rectangle structure variable named box. cout   Exercise 1: Fill in the code as indicated by the comments in bold. Exercise 2: Modify the program above by adding a third structure named results which has two members area and perimeter. Adjust the rectan- gle structure so that both of its members are structure variables Exerise 3: Modify the program above by adding functions that compute the area and perimeter. The structure variables should be passed as arguments to the functions. Lesson 11B 211 Sample Run: Enter the length of a rectangle:9 Enter the width of a rectangle: 6 The area of the rectangle is 54.00 The perimeter of the rectangle is 30.00
