Area is length times width, perimeter is twice the sum of length and breadth.

Let's take a look at this problem.Rectangle Perimeter = 2(l + w)Rectangle Perimeter =? 2(2l + 2w)Rectangle Perimeter =? (2)(2)(l + w)2(Rectangle Perimeter) = 2[2(l + w)]Thus, we can say that the perimeter of a rectangle is doubled when its dimensions are doubled.Rectangle Area = lwRectangle Area =? (2l)(2w)Rectangle Area =? 4lw4(Rectangle Area) = 4lwThus, we can say that the area of a rectangle is quadruplicated when its dimensions are doubled.


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.


No. For example, a 4x1 rectangle will have an area of 4 and a perimeter of 10. A 2x2 rectangle will have the same area of 4, but a perimeter of 8.


The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.


The perimeter of the rectangle is the sum of its 4 sides.


find the perimeter and area of a rectangle that is 15cm long and 5cm wide


the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle


No,for example, a 1x2 rectangle has an area of 2 but a perimeter of 6


Yes, the perimeter or area of a rectangle can be an irrational number. Thanks


156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and width.


how do you find the area of a rectangle witha perimeter of 36 in You don't. You need more information For example a 1 x 17 rectangle has a perimeter of 36 and its area is 17. But a 2 x 16 rectangle also has a perimeter of 36 and its area is 32.


The perimeter of rectangle A would then be 80 because 80 to 100 is 4 to 5 simplified and the area of triangle A would depend on the sides and area of rectangle B which have not been given.



what are the dimensions of the rectangle with this perimeter and an area of 8000 square meters


Definitely.Rectangle #1: 18 x 2Perimeter = 40Area = 36Rectangle #2: 7 x 6Perimeter = 26Area = 42Rectangle #2 has a less perimeter than #1,but more area.


Yes. For instance, the rectangle measuring 1 by 10 has a perimeter of 22 and an area of 10, whereas the rectangle measuring 4 by 4 has a perimeter of 16 and an area of 16.


What is a rectangle were the area is 10 and the perimeter


That depends on the dimensions !... A 1 x 18 rectangle has a perimeter of 38 ! A 2 x 9 rectangle has a perimeter of 22 ! A 3 x 6 rectangle has a perimeter of 18 !


Rem to Find area and rectangle of a rectangle Input "Length?",l Input"Breadth?",b let area=l*b let perimeter=2*l+b ?area ?perimeter



For a fixed perimeter, the area will always be the same, regardless of how you describe the rectangle.


Perimeter = 24 and area = 27 . . . . . rectangle, 3 by 9 Perimeter = 32 and area = 15 . . . . . rectangle, 1 by 15


To answer this simply try a few out for yourself. In a 2x1 cm rectangle, the area is 2 cm squared and the perimeter is 6 cm In a 12x10 rectangle, the area is 120 cm squared and the perimeter is 44 cm. In some cases, the perimeter is larger and in others it is smaller. To answer your question, no, the perimeter of a rectangle is NOT always greater than its area.


the area and perimeter of the plane figures are square ,rectangle


To find the perimeter you add and to find the area we multiply.
