Answer: the length of the pool is 22.5 feet.
the width of the pool is 16.5 feet.
Step-by-step explanation:
The swimming pool is rectangular in shape.
Let L represent the length of the rectangle.
Let W represent the width of the rectangle. The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter of a swimming pool is 78 feet. This means that
2(L + W) = 78
L + W = 78/2 = 39
The difference between four times the length and the width is 73.5 feet. This means that
4L - W = 73.5 - - - - - - - - - - - 2
Substituting W = 39 - L into equation 2, it becomes
4L - (39 - L) = 73.5
4L - 39 + L = 73.5
4L + L = 73.5 + 39
5L = 112.5
L = 112.5/5
L = 22.5
W = 39 - L = 39 - 22.5
W = 16.5
You know that the area of a triangle is (h*b)/2
if we know the area we will have 558= (h* 36)/2
or 558*2= h*36
h=(558*2)/36=31
h=31
The area of the park without fountain is about 819.76 square yards.
Answer:
26
Step-by-step explanation:
4(x-4)-3x=10
- Rule = a(b + c) = ab + ac
- Rule = a(b - c) = ab - ac
4(x-4) = 4x - 16
4(x-4)-3x=10
4x - 16 - 3x = 10
x - 16 = 10
x -16 +16 = 10 +16
x = 26
Hope this helps ^-^
