What is the formula for the perimeter of a equilateral triangle?

Add the lengths of each side together to get the perimeter.


What is the formula to find the length of a rectangle when the perimeter and width is already given?

Length = (Perimeter - twice width) / 2


What formula expresses the perimeter of a rectangle in terms of its length?

The formula for the perimeter of a rectangle is: p = 2(l + w) In other words, just add all four sides. You can't calculate the perimeter of the rectangle if you know only the length.


Explain why the formula for the perimeter of a rectangle and the formula for the perimeter of a square are different?

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.


What is the largest area that you can have if the perimeter is 24 feet?

You get the largest area with a circle. Divide the perimeter by (2 x pi), then calculate the area with the formula pi x radius2.You get the largest area with a circle.
