if the perimeter is 12 then the semi perimeter is 6
p=2L+2w
12=2L+2w
by division
6=L+w

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.
Explain how to find a perimeter of the rectangle?
Add up the lengths of all the sides. Since there are two pair of equal sides, just take each the length and double it and then the width and double it. Now add those two numbers. If the length is L and the width is W, the perimeter is 2L +2W
If two rectangles have the same area do they have the same perimeter too explain how you know?
Not necessarily. For instance If you take two rectangles whose area's are 36in squared. One could be 6 by 6 while the other could be 9 by 4. Thus ones Perimeter would be 24in with the others would be 26in.
Is the area of one triangle a rational number or an irrational number Explain.?
The area of a triangle can be a rational number or an irrational number depending on its dimensions.
Are all rectangles congruent Explain your answer?
yes, all rectangles are in fact congruent. they're all congruent because its a ratio of sizes. if u have a rectangle with a length of 5 and a width of 2.5, and an another rectangle with a length of 10 and a width of 5, u have a ratio of sixes. the ratio would be 1:2. hope it helps (:
The area of a rectangle is 100 inches the perimeter is 40 a second rectangle has the same area but a different perimeter. Is the second rectangle a square?
the area of a rectangleis 100 square inches. The perimeter of the rectangle is 40 inches. A second rectangle has the same area but a different perimeter. Is the secind rectangle a square? Explain why or why not.
Why it's not possible to have a perimeter of 20 units with an area of 18 square units?
That would be very difficult to explain, because it's not true. Consider this rectangle: Length = 7.64575 units Width = 2.35425 units Perimeter = 20 units Area = 18 square units =================================== Precise dimensions are: 5 + sqrt(7) 5 - sqrt(7)
Can a rectangle have the same perimeter but different area explain?
No, any shape with four sides and same perimeter will always be a square.
Is there a relationship between the area and the perimeter of a rectangle explain?
Yes, there is. The area of a rectangle sets a lower limit on its perimeter.If the area is A, then the quadrilateral shape with the smallest perimeter has sides of length sqrt(A). Therefore the minimum perimeter is 4*sqrt(A). The perimeter can have any value grater than that since the area of the rectangle can be maintained while making it thinner and longer and thus increasing its perimeter with out any upper limit.
Explain how you could use grid paper to draw a rectangle with a perimeter of 18 units?
i dont know the anwser
What happens to the perimeter and the area of a rectangle if the length and the width are multiplied by the same number Use diagrams to explain?
If the length and width of a rectangle are multiplied by the same number, then . . . -- the perimeter is multiplied by the same number -- the area is multiplied by the square of the numbner
Formulate a rectangle with sides 7 inches and 3 inches long. Explain the perimeter and area of the rectangle.?
Perimeter: 7+3+7+3 = 20 inches Area: 7 times 3 = 21 square inches

I think if it were to be a triangle that it would be six on each
