Question

construct a parallelogram PQRS with PQ=4cm, QR=5.5cm and angle P=70°​

Answer 1

Step-by-step explanation:

1. We know that opposite sides and angle of parallelogram are equal.

2.And adjacent angles of parallelogram are supplementary. By using these properties we are going to construct a parallelogram.

3. Draw a line segment pQ=5cm

4. Construct an angle of 70 at point Q.

5.Cut off QR=4cm

6.Join RS

7.Thus PQRS is a required parallelogram.

8.Let a = 5cm and b = 4cm

9.Perimeter of parallelogram PQRS = 2(a+b) = 2(5+4) = 8

10.The perimeter of parallelogram PQRS = 18 cm
