    The perimeter is just the sum of all sides. If you have a square of length 8, then you have 4 sides, that's 8 +8 + 8 +8

    just do 2l+2w=P

    so 2(8)+2(8)=P or do l^2 8^2=P

    That's the formula for the perimeter of a rectangle, @jacobrocket173 and it is the same thing as I said: sum of all sides.

    or you can just do 4(8)=P...

    2(0.85)+2(0.4)=P

    Same thing, draw out the rectangle. Which has 4 sides, so you know youre going ot be adding two of the same sides and 2 of other same sides. Use: \(\sf \color{blue}{2l + 2w}\)

    thanxs now What is the perimeter of the polygon? A. 18 in. B. 36 in. C. 54 in. D. 108 in.|dw:1443013742394:dw|

    the 2 comes from the fact that you have two sides of equal length. Remember that in a rectangle, two sides are the same. |dw:1443024607773:dw|

    Same for the polygon. PERIMETER just means \(\sf \color{red}{sum}\) of all sides. Add up all the sides!

    wait i have already ask that question i mean Which equation could be used to find the perimeter of a rectangle that has a width of 18 ft and a length of 24 ft? A. P = 18 · 24 B. P = 2 · 18 + 24 C. P = 2 · 18 + 2 · 24 D. P = 16 + 24
