Square Class

Create a square class defined by the following

• Property
  • side
• Methods
  • perimeter (side times 4)
  • area (side squared)
  • diagonal (square root of 2 * side squared)
  • describe – shows the squares information as follows:

Square with side 2 has perimeter of 8, area of 4, and diagonal of 2.828

Your program is to create three squares and use the describe method to show each squares information.

Answer 1

class Square {
//constructor to set the side of the square
constructor(side){
this.side = side;
}

//method that returns perimeter of square
perimeter(){
return 4 * this.side;
}

//method that returns area of square
area(){
return this.side * this.side;
}

//method that returns diagonal of square
diagonal(){
return Math.sqrt(2 * this.side * this.side).toFixed(3);
}

//method that returns a string describing the square
describe(){
return "Square with side "+this.side+" has perimeter of "+this.perimeter()+", area of "+this.area()+", and diagonal of "+this.diagonal();
}
}

//creating square of side 2
square1 = new Square(2);
console.log(square1.describe());

//creating square of side 3
square2 = new Square(3);
console.log(square2.describe());

//creating square of side 4
square3 = new Square(4);
console.log(square3.describe());

Code Snippet:

class Square {
  //constructor to set the side of the square
  constructor(side){
    this.side = side;
  }

  //method that returns perimeter of square
  perimeter(){
    return 4 * this.side;
  }

  //method that returns area of square
  area(){
    return this.side * this.side;
  }

  //method that returns diagonal of square
  diagonal(){
    return Math.sqrt(2 * this.side * this.side).toFixed(3);
  }

  //method that returns a string describing the square
  describe(){
    return "Square with side "+this.side+" has perimeter of "+this.perimeter()+", area of "+this.area()+", and diagonal of "+this.diagonal();
  }
}

//creating square of side 2
square1 = new Square(2);
console.log(square1.describe());

//creating square of side 3
square2 = new Square(3);
console.log(square2.describe());

//creating square of side 4
square3 = new Square(4);
console.log(square3.describe());
