The length of a rectangular swimming pool is p m and its width is q m. It is given that the length of the swimming pool is twice its width. If the perimeter of the swimming pool is 150 m, find the values of p and q.

Respuesta :

Answer: q = 25 m, p = 50 m

Step-by-step explanation:

  1. p is the length, and q is the width.
  2. Since the length is twice as long as the width, we can come up with the equation: p = 2q
  3. Since the perimeter is 150, we can also come up with this formula since the perimeter is all sides added together: 2p + 2q = 150
  4. Since we have two equations, we can just plug them into each other. First, let's substitute the 2q in the second equation with p that is defined in the first equation: 2p + p = 150
  5. If we simplify that, we get: 3p = 150
  6. Now we know that p = 50 m.
  7. Now, if you plug in 50 into the first equation you get: 50 = 2q.
  8. Next, just simplify, and you know that q = 25 m.
  9. Therefore, p = 50 m, q = 25 m.
