how can I calculate the premitere of a triangle, rectangle and a square?

Answer 1

For each and any regular shape in general, Add the lengths of each side altogether and you'll get the premitere.

Answer 2

The perimeter of shapes is the length of all the sides.

If a square has a side of length A, then the perimeter is 4A (because a square has four identical sides).

If a rectangle has long sides of length B and short sides of length C, then the perimeter is 2B + 2C (since it has two sides of each). Note that since a square is a special type of rectangle, this formula works for a square as well.

If a triangle has sides of D, E, and F, then its perimeter is D+E+F. There may be other special formulae that work if it's a special kind of triangle.

Answer 3

perimeter of the square is 4 x the length 4l
the perimeter of a rectangle is 2 x(l+w)
a triangle is funny, just add the length of all three sides.
for an equilateral is 3xl
for isosceles is B+(2xslope) b is base length.

Answer 4

Perimeter of rectangle = 2(l+b)
Perimeter of square = 4s
Perimeter of triangle = side1 +side2+side3

Answer 5

Triangle is side1+side2+side3
rectangle2(length+breadth)
square 4*any side

Answer 6

Perimeter of Triagle = a+b+c

Rectangle = 2(a+b)

Square = 4a

Answer 7

I Don't Know, but I seen you had no answers, so I thought I would tell you that..... I Don't Know. I could not tell you for a Million Dollars Cash. LOLOL......Good Luck with that...Peace
