I'm going to refer to the length of the pool as L.
2x + 2L = perimeter.
The width of pool multiplied by two added to the length of the pool multiplied by two equals to the perimeter.
Answer:
Perimeter = Side1 + Side2 + Side3
4x + 3y = 5x - 3y + x + 4y + Side3
4x + 3y = 6x + y + Side3
-2x + 2y = y + Side3

Step-by-step explanation:
The sum of 83 and a number would be
as an expression, where
is "said number".
(-12 - 2i) + (2 + 2i)
= -12 - 2i + 2 + 2i
= -12 + 2 - 2i + 2i
= -10
Answer: -10
Area of the bottom triangle = 1/2 x 10 x 8.7 = 43.5 cm²
Area of the 3 rectangles = 3(10 x 6) = 180 cm²
Area of the top triangle = 3 (1/2 x10 x 4) = 60 cm²
Total surface are = 43.5 + 180 + 60 = 283.5 cm²
Answer: 283.5 cm²
