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. (**please use the simultaneous linear equations in two variables to solve this question)
**if you have answer this question I will choose you to be the brainlest answer**
Since the length is twice as long as the width, we can come up with the equation: p = 2q
Since the perimeter is 150, we can also come up with this formula since the perimeter is all sides added together: 2p + 2q = 150
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
If we simplify that, we get: 3p = 150
Now we know that p = 50 m.
Now, if you plug in 50 into the first equation you get: 50 = 2q.
