We can define variable as<span> any factor, trait, or condition that can exist to vary or change. </span> Perimeter of rectangle = 2(l+w) let l is the length of the garden and w is the width of the garden =<span> 6 less than the length = l - 6 perimeter = 188 feet p = 2(l+w) 188 = 2 (l + (l-6)) 188 = 2(l + l - 6) 188 = 2(2l-6) 188 = 4l - 12 4l = 188+12 4l = 200 l=50 w = l - 6 = 50 - 6 = 44 Thus, the dimensions, length is 50 feet and width is 44 feet.</span>
<span>Let L = length. Therefore, by given information the width, W, is equal to L-6. Perimeter = 2*length + 2*width or 2L+2W.
Substitute in values we get 188 = 2*L + 2*(L-6)
Expand: 188 = 2*L + 2*L - 12
Add 12 to both sides and combine like terms: 200 = 4*L
Divide both sides by 4: 50 = L
The length if found to be 50 feet. The width is then 50 - 6, or 44 feet.
We can confirm that the perimeter is 50+50+44+44 feet, or 188 feet.</span>
