Answer:
112 in^2
Step-by-step explanation:
10 x 10 = 100
4 x 6 / 2 = 12
112 inches squared
The numbers 1 to 72 add up to (1+72) x 72/2 = 73 x 36 = 2628
If we take away what Josh got we have 2628 - 2521 = 107
Pages in a book are odd on the first side and even on the second, so pages 11 and 12 are on the same sheet.
107 / 2 = 53.5 so the missing page had 53 on one side and 54 on the other side.
The remaining pages would have been numbered 1, 2, 3, ..., 51, 52, 55, 56, ... 71, 72

By definition, an obtuse triangle has an obtuse angle (angle greater than 90 degrees). The 3 angles of a triangle always add up to 180 degrees. Since one of our angles is greater than 90 degrees, the other 2 have to add up to less than 90 degrees, so there can be NO RIGHT ANGLES.
