yes

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

i dont no if you can find the perimeter of a triagle by using subtration the formula is adding all the up together.

You cannot find the perimeter unless the rectangle is a regular rectangle (a square) in which case the perimeter is 4 times the square root of the area. With just the area the shape of the rectangle could be any number of shapes with different perimeter, for example, imagine 6 square units 1cm by 1cm arranged in a 1*6 configuration to give a long thin rectangle, the perimeter would be 6+6+1+1=14cm, the same 6 arranged in a 3*2 rectangle would have the same area, but a perimeter of 3+3+2+2=10cm, for this reason a rectangle's perimeter cannot be determined from the area alone.

The perimeter of the rectangle is 2•66+2•32=196196/4(sides of a square)=49 cm

I think so

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.

Length = (Perimeter - twice width) / 2

98 square feet

Measure and add together the 4 sides
