Sorry, maybe is too late for you, But the answer is: For example: 4 x 4=16cm² if <span> one pair of opposite sides was made 50% longer and the other pair of opposite sides was made 50% shorter It became: 6 x 2=12cm</span>² 12/16=0.75 So, the 75% <span>of the square’s area is the area of the new rectangle.</span>
Let the total amount of pages be t t=30+1/8t+2/8t now simplify t=30+3/8t 5/8t=30 divide 30 by 5 1/8=6 now you know 1/8 of the book is 6 pages which means the whole book has 48 pages.
