Question

measure the length of RS =--------cm​

Answer 1

According to the property of trapezium, PQ must be parallel to RS.

So, AS = RB

PSsin60=QRsin30PS=2.3×sin60sin30PS=1.3

From the figure, it is clear that,

RS = PQ-(PA+QB)

RS=PQ−(PScos60+QRcos30)RS=5−(1.3cos60+2.3cos30)RS=2.3

Answer 2

Answer:

the length of RS can be found by using a string. mark a point on the string, keep it on R and bring it till S. now measure it with ruler. it is the required length.
