We have been given that
Luke can read 4 3/4 pages in 15 minutes.
Hence in 1 minute Luke can read 19/60 pages.
Sarah can read 1 1/2 pages in 4 minutes.
Hence, in 1 minute Sarah can read 3/8 pages.
Now, let us find how many pages they can read in 2 hours = 120 minutes.
In 2 hours Luke can read pages.
In 2 hours Sarah can read pages.
The difference in the number of pages is 45 - 38 = 7 pages.
Therefore, Sarah can read 7 more pages than Luke in 2 hours.

Answer:
9. 108 cm^2 or B
10. 1,080 m^2 or B
Step-by-step explanation:
9.
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=3·8+4·8+5·8+1
2·﹣34+2·(3·4)2+2·(3·5)2﹣44+2·(4·5)2﹣54
= 108
10.
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=15·24+8·24+17·24+1
2·﹣154+2·(15·8)2+2·(15·17)2﹣84+2·(8·17)2﹣174
= 1080
