0. PQRS is a parallelogram. QM is the height from Q to SR and QN is the height from Q to PS. If SR=12 cm and QM=6 cm ,find:
a) The area of parallelogram PQRS
b) The length of QN, if PS=8 cm.

Step-by-step explanation:

Given: SR=12cm, QM=7.6cm, PS=8cm.

Area of parallelogram=base×height

=12×7.6=91.2cm2.

Area of parallelogram=base×height

⇒91.2=8×QN

⇒QN= 9.12/8 = 11.4cm.

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
