7. A. U and V
8. Writes length and breadth, which are greater than zero and less than 70, with or without the word ‘Chapter(s)’
● Length 21 and breadth 7
● 21 units and 7 units
● 69 units and 1 Chapter
9. D. $\sqrt{580}$ units
10. Due consideration is given to factors including display dimensions and orientation (portrait/landscape) 2 x y z with or without the word ‘units’
● The manufacturer needs to know the space available for the screen installation along with the screen size.
● Length and breadth, along with orientation, is to be considered.
