A rectangle has a circumference of 40 cm. If you increase the width by 2 cm and shorten the length by 3 cm, the area will be 1 cm2 smaller. Calculate the original area.

Consider an example of a deck of 52 cards: example set of 52 playing cards: 13 of each suit clubs, diamonds, hearts, and spades ace 2 3 4 5 6 7 8 9 10 jack queen king clubs diamonds hearts spades what is the probability of drawing three queens from a standard deck of cards, given that the first card drawn was a queen? assume that the cards are not replaced.
