The perimeter of a rectangular swimming pool is 414 meters. The length of the pool is 7 meters more than four times the width. Find the length and the width.

Length= 167 meters, Width= 40 meters

Step-by-step explanation:

We know that perimeter is the lengths of all sides of the rectangle added together. Therefore, the formula for perimeter is . We can use system of equations to find length and width.

The second equation comes from the fact that the length is 7 meters more than 4 times the width.

Since we know the equation of , we can use substitution to find and .

The problem gives us the perimeter to we can plug that into P.

Now that we know the width, we can plug it into the equation to find length.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
