In formation of square and rectangle we will learn how to construct square and rectangle.
We follow the method given below.

Step I: We draw a line segment AB of the required length.
Step II: We draw the right angles at both end points A and B on the line segment AB.
Step III: We cut off the sides of the square AD and BC, equal to AB, on both the perpendicular lines drawn at points A and B on line segment AB.
Step IV: Now we join the points A and D, B and C and D and C to form the required square.
We follow the same method as described above.

Step I: After drawing perpendicular lines at points A and B on the line segment AB, we cut off the required breadth of the rectangle AD and BC from both the perpendicular lines.
Step II: Now we join the points A and D, B and C and D and C to form the required rectangle.
1. Construct the square of the following lengths.
2. Construct the rectangles of the following lengths and breadths. Find their perimeters also.
