You can't tell. The perimeter doesn't tell you the area. There are an infinite number of rectangles that

all have the same perimeter but different areas. Here are a few that all have perimeters of 28 cm:

1 x 13 . . . . . Area = 13

2 x 12 . . . . . Area = 24

3 x 11 . . . . . Area = 33

4 x 10 . . . . . Area = 40

5 x 9 . . . . . Area = 45

6 x 8 . . . . . Area = 48

7 x 7 . . . . . Area = 49

What is the perimeter of a square if it has an area of 49 centimeters squares?

Area of a square can be calculated using the formula A = a^2, where "a" is the length of a side of the square. Its perimeter is P = 4*a. 49 = a^2 => a = 7cm P = 4*7 = 28cm The perimeter of the square is 28cm.

If same area in a rectangle does that mean same perimeter?

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.


What is perimeter and area called in mathematics?

The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.

What is the effect on the perimeter of a rectangle if the dimension are doubled what is the effect on its area?

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.
