Answered by Kuai

90 minutes = 1.5 hrs
45 minutes = 0.75 hrs

8*5 - (1.5 + 0.75 + 2.5 )
40 - 4.75
35.25 = 35 1/4 hours = 35 hours and 15 minutes

Width of pool is x+3
Length of pool is 3x-4

Width of deck is 3x-2
Length of deck is 2x+6

area= (2x+6)(3x-2) - (3x-4)(x+3)

= 6 x^2 + 14 x -12 -[ 3x^2 +5 x -12 ]

= 3 x^2 + 9 x
