The pool cover consist of three rectangles, which can be redraw as,
The dimensions of rectangle are,
Rectangle 1: 7.5 ft by 10 ft.
Retangle 2: 12.5 ft by 45 ft.
Rectangle 3: 8 ft by 7.5 ft.
Determine the area of pool cover by addition of area of rectangle 1, 2 and 3.
[tex]\begin{gathered} A=10\cdot7.5+45\cdot12.5+7.5\cdot8 \\ =75+562.5+60 \\ =697.5 \end{gathered}[/tex]
Thus area of pool cover is 697.5 feet square.
