If 2 different rectangles have the same perimeter why is the area different for each?

Perimeter = 2 x (length + width), area = Length x width. Perimeter is not directly related to area except in the cases of circles and squares.
Consider a rectangle of 60 sq cm: the integer possibilities for length and width are numerous: 1 x 60, 2 x 30, 3 x 20, 4 x 15, 5 x 12 and 6 x 10.
The respective perimeters are 122 cm, 100 cm, 46 cm, 38 cm, 34 cm and 32 cm.
Note that the nearer the shape becomes to a square, the smaller the perimeter. (A square would have a perimeter of a whisker under 31 cm.)

What is the area and perimeter of a large square if two congruent rectangles are arranged so they from a square with each perimeter of rectangles is 36 inches?
area = 144 square units perimeter = 48 units
How are area and perimeter different from each other?
The perimeter is the outside of a shape and the area is the inside of it
How do you work out perimeter and area?
It is different for each shape. A perimeter is the distance around an object and the area is the square units it takes up.
Two rectangles have an area of 81 square inches name two possible perimeter for each rectangle?
3*27 = 81 and 3+3+27+27 = a perimeter of 60 inches
How many rectangles each having a perimeter of 36 cm can be drawn?
Depends what you are drawing on.

If two rectangles have the same area do they also have to have the same perimeter?
Not necessarily. Let's say that there is a circle with the area of 10. Now there is a star with the area of 10. They do not have the same perimeter, do they? That still applies with rectangles. There might be a very long skinny rectangle and a square next to each other with the same area, but that does not mean that they have the same perimeter. Now if the rectangles are congruent then yes.

What is the area of a rectangle with a perimeter of 42cm?
You can't tell the area from knowing the perimeter. There are an infinite number of different rectangles, all with the same perimeter, that all have different areas. Here are a few rectangles that all have perimeters of 42. The last number after each one is its area: 1 cm by 20 cm . . . . . 20 square centimeters 2 x 19 . . . . . 38 3 x 18 . . . . . 54 4 x 17 . . . . . 68 5 x 16 . . . . . 80 10 x 11 . . . 110

Two rectangles have a perimeter of 16 inches Name two possible areas for each rectangle?
* It is unclear if the question is asking about two rectangles, each with a perimeter of 16, or two rectangles whose perimeters sum to 16. This answer assumes the former.Other than the 4x4 square, which coincidentally has both a perimeter and area of 16, some examples would be:1 x 7 rectangle : perimeter 16 in. , area 7 sq. in2 x 6 rectangle : perimeter 16 in., area 12 sq. in3 x 5 rectangle: perimeter 16 in., area 15 sq. inYou can calculate that for a given perimeter, the largest area is found in the square with a side measurement of P/4, i.e. the length and the width are the same.
Two rectangles have an area of 81 square inches name two possible perimeter for each rectangle?
3*27 = 81 and 3+3+27+27 = a perimeter of 60 inches
How many rectangles each having a perimeter of 36 cm can be drawn?
Depends what you are drawing on.
There are two rectangles a triangle and half a circle find the total area?
The answers depend on what measures are available for the rectangles (sides, diagonals), for the triangle (3 sides, 2 sides and included angle, one side and 2 angles), and for the circle (radius, perimeter). In each case the formula to be used will be different.
Two rectangles have an area of 81 square inches Name one possilble perimeter for each rectangle?
4.5*18 = 81 and 4.5+4.5+18+18 = a perimeter of 45 inches 3*27 = 81 and 3+3+27+27 = a perimeter of 60 inches
How many rectangles can you draw with a fixed perimeter of 15 cm but having each one a different area?
An infinite amount. You need to specify down to what decimal point. I.e. 4+3.5+4+3.5 = 15, area = 14cm^2. 4.000001+3.499999+4.000001+3.499999=15, area = 13.9999995cm^2
How do you find the perimeter area of a box?
Perimeter=find each perimeter of each side of the box then add them all up area=find each are of each side of the box then add them all up
