Assume you are given a boolean variable named isrectangular and a 2-dimensional array that has has been created and assigned to a2d. write some statements that assign true to isrectangular if the entire 2-dimensional array is rectangular, meaning every row has the same number of elements as every other row.

nElements = 0;

for (int i = 0; i < a2d.length; i++)

nElements += a2d[i].length;

isRectangular = true;

for (int i = 1; i < a2d.length && isRectangular; i++)

if (a2d[i].length != a2d[0].length)

isRectangular = false;

Step-by-step explanation:

2 dimensional array is created and  initialize element with 0. and the taking loop for 2 dimensional array .such as

n Elements = 0;

for (int i = 0; i < a2d.length; i++)

n Elements += a2d[i].length;

A boolean variable isRectangular and 2 dimensional array has been created if rectangle is true the take a2d.length and isRectangular less than i and intiliaze i with 1 then increment the i .It will give true value.

If rectangular is false then  apply if statement  and see if a2d[i] is not equal to a2d[0]

if (a2d[i].length != a2d[0].length)

isRectangular = false;
