The courtyard of a castle is in the shape of a square. Given that one side of the courtyard is 41 feet, determine its area in square feet.
We know that a square has four sides of equal length. In this question, we’re told that one side of the courtyard is 41 feet in length. This means that all four sides must be 41 feet in length. The area of any square can be calculated by squaring the side length. In this question, we need to square 41. As squaring a number involves multiplying it by itself, we need to multiply 41 by 41.
One way of doing this would be to multiply 41 by 40, 41 by one, and then adding the answers. As 40 multiplied by 40 is 1600, 41 multiplied by 40 is 1640. 41 multiplied by one is 41. Adding these gives us 1681. As the length of the courtyard was given in feet, the area will be in square feet.
We can, therefore, conclude that the area of the courtyard is 1681 square feet.
