Construct a rectangle whose adjacent sides are 5.6cm and 4cm.

Hint: Knowing about the sides of the rectangle. By knowing sides and angles we can construct the rectangle. There are certain properties to be followed to construct a rectangle. By knowing the properties construction becomes easier.

Complete step-by-step answer:
Rectangle: Opposite sides are equal in rectangle.
                   It is a quadrilateral with four right angles.
                  Diagonals will be of equal length.
                  Diagonals bisect each other.
                  All the angles are equal in case of rectangle.
                  From the bisecting diagonals two right angled triangles are formed.
Steps for construction:
First draw the base 5.6cm ... (1)
After this draw a line segment perpendicular to the base with 4cm ... (2)
Now from the above a line segment is drawn perpendicular to the 4cm line … (3)
Drawing 4cm to close the figure ... (4)



From the above steps of construction we have drawn a rectangle with 5.6 cm as base and perpendicular to this 4cm is drawn.
Following those (1), (2), (3), (4) steps leads to the construction.

Note: We should know the properties of a rectangle before construction because without knowing them we cannot proceed how the image looks like. Opposite sides are equal in rectangle. This is the main point in construction.
