3) A local grocery store has plans to construct a rectangular parking lot on land that is bordered on one side by a highway. There are 1280 feet of fencing available to enclose the other three sides. Find the dimensions that will maximize the area of the parking lot. (All the equations must be solved using MATLAB). 4) Write a program using a single while loop (no for loops, if else, switch, break, conditional statements inside the while loop) that finds the smallest even integer that is divisible by 12 and whose square root is greater than 100. The loop should start from 0 and stop when the number is found. The program prints the message "The required number is:" and then prints the number
