Question

Construct a rectangle whose adjacent sides are of lengths 5 cm and 3.5 cm.

Geometric Constructions

Solution 1

We know that, each angle of a rectangle is right angle (i.e., 90°) and its opposite sides are equal and parallel.

To construct a rectangle whose adjacent sides are of lengths 5 cm and 3.5 cm, use the 1 following steps:

1. Draw a line segment BC of length 5 cm.

2. Now, generate an angle of 90° at points B and C of the line segment BC and plot the parallel lines BX and CY at these points.

3. Cut AB and CD of length 3.5 cm from BX and CY, respectively.

4. Draw an angle 90° at one of the point A or D and join both points by a line segment AD of length 5 cm.

Thus, ABCD is the required rectangle with adjacent sides of length 5 cm and 3.5 cm.

Solution 2

To construct a rectangle ABCD whose adjacent sides are of lengths 5 cm and 3.5 cm, use the following steps:

1. Draw a line segment SC of length 5 cm.

2. Now, draw an ∠XBC = 90° at point B of line segment SC.

3. Cut a line segment AB = 3.5 cm from the ray BX and join AC.

4. Now, from A, point D is at a distance of 5 cm. So, having A as centre draw an arc of radius 5 cm.

5. From C, point D is at a distance of 3.5 cm. So, having C as centre draw an arc of radius 3.5 cm which intersect previous arc (obtained in step iv) at D.

6. Join AD and CD. Thus, ABCD is the required rectangle with adjacent sides of length 5 cm and 3.5 cm.
