The area of the rectangle doesn't tell you the perimeter. There are an
infinite number of different rectangles with different perimeters that all
have the same area.
Here are a few rectangles and their perimeters.
They all have areas of 36:
1/2 x 72 .. . 145
1 x 36 . . . . . 54
1.5 x 24 .. . . 51
2 x 18 . . . . . 40
2.5 x 14.4 . . 33.8
3 x 12 . . . . . 30
3.6 x 10 .. . . 27.2
4 x 9 . . . . . . 26
4.5 x 8 .. . . . 25
6 x 6 . . . . . . 24
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.

A rectangle that's 7 x 1 inches has a perimeter of 16inches,and its area is 7 square inches.A rectangle that's 5 x 3 inches also has a perimeter of 16 inches,but its area is 15 square inches.A rectangle that's 6 x 2 inches also has a perimeter of 16 inches,but its area is 12 square inches.A square that's 4 inches on each side also has a perimeter of 16 inches,but its area is 16 square inches.A circle that's 16 inches around the outside also has a perimeter of 16 inches,and its area is 20.4 square inches.There's no reason why there has to be a connection between perimeter and area.

If that's a rectangle, the perimeter is 24 inches and the area is 27 square inches.
Perimeter: 7+3+7+3 = 20 inches Area: 7 times 3 = 21 square inches
The square's area is 36 in2 while the rectangle's is 32. So the square has the greater area.
If the perimeter of a square is 28 inches the area is: 49 square inches.
