THE LENGHT OF A SQUARE GARDEN IS TWICE A NUMBER. IF THE PERIMETER OF THE GARDEN IS 36, FIND THE NUMBER
Let side of square be=l
Given,
perimeter=36
ATQ
4l=36
l=36/4
l=9
i.e length of square garden is 9
so the number is=9*2
=18
Ans:18
4*9 = 36
so garden length is 9
so n = 4.5
It said the length was twice, not half.
To find the number, we first need to set up an equation based on the given information.
Let's assume that the number is 'x'.
According to the given information, the length of the square garden is twice this number. So the length of the square garden would be 2x.
We know that the perimeter of a square is given by the equation:
Perimeter = 4 * side length
In this case, the perimeter of the garden is given as 36. So we can set up the equation:
36 = 4 * side length
Since the garden is a square, the length and width are the same, so we can substitute the side length with the length of the garden, which is 2x.
Substituting this value into the equation, we get:
36 = 4 * 2x
Now we can solve for x:
Dividing both sides of the equation by 4 gives:
36/4 = 8x/4
Simplifying further, we have:
9 = 2x
Now, divide both sides by 2 to isolate x:
9/2 = 2x/2
Simplifying, we get:
4.5 = x
Therefore, the number is 4.5.
