The perimeter of a pool table is about 7.8m. Four times the length equals nine times the width. What are the dimensions?
I need to find 2 equations first.
I got 2l + 2w= 7.8
I cant seem to get the other one
To find the second equation, you can use the given information that "four times the length equals nine times the width." Let's denote the length as 'l' and the width as 'w'.
The equation for the given information can be written as:
4l = 9w
Now, you have two equations:
1) 2l + 2w = 7.8 (from the perimeter information)
2) 4l = 9w (from the length and width relationship)
These two equations can be solved simultaneously to find the dimensions of the pool table.
In order to find the other equation, we need to use the information provided in the second sentence: "Four times the length equals nine times the width." Let's break this down into an equation.
Let's assume the length of the pool table is represented by "l" and the width is represented by "w."
According to the given information, four times the length (4l) is equal to nine times the width (9w). This can be expressed algebraically as:
4l = 9w
Now we have two equations:
1) 2l + 2w = 7.8 (perimeter equation)
2) 4l = 9w (dimension equation)
We can solve these equations to find the dimensions of the pool table.
4l=9w is the other equation
the dimensions should be
l=2.7
w=1.2
