what is a function rule for the perimeter P of a building with a rectangular base if the width w is 2x the length l?
y=-10,for x=2
Usually, the width is shorter than the length. However, assuming that youa re correct in the width being twice the length.
Perimeter is 2l + 2w = P.
Since 2l = w, you can substitute w for 2l.
Giving w + 2w = P, so
3w = P.

If the width is 2L than 2L+2L+L+L than P=6L.
To find the function rule for the perimeter (P) of a building with a rectangular base, where the width (w) is 2 times the length (l), we need to determine how the perimeter is affected by the dimensions of the building.
The perimeter of a rectangle is given by the formula: P = 2(l + w), where l represents the length and w represents the width.
Since we know that w is 2 times the length (w = 2l), we can substitute this value in the equation:
P = 2(l + 2l)
Simplifying the expression within the parentheses:
P = 2(3l)
Now, we can further simplify the equation:
P = 6l
Therefore, the function rule for the perimeter (P) of a rectangular building, where the width (w) is 2 times the length (l), is P = 6l.
