I think so
Square is a special case of a rectangle and the same formula may be used to find the perimeter
no
yes
Yes. But using P=4s is easier with a square.
When you think about it for a while, they're really NOT different. The rectangle formula needs a bit more detail, because its sides don't all have the same length, so its length and its width have to be handled separately. But the rectangle formula works perfectly well if you use it to find the perimeter of a square.
The formula for the perimeter of a rectangle with length L and width W is P = 2*(L + W) In a square, the length and width are the same. So L = W And so A = 2*(L + L) = 2*(2L) = 4*L
It is the sum of their 4 sides
In order to find the perimeter of a 3D rectangle you must gather the lengths of the known sides, calculate the missing rectangular values, and use the formula for perimeter.
98 square feet
Length = (Perimeter - twice width) / 2
i dont no if you can find the perimeter of a triagle by using subtration the formula is adding all the up together.
Measure and add together the 4 sides
