### If you know a perimeter of a square but not the length or width how do you find the area?

Divide the perimeter by 4 and then square the result to find the area of the square.

### Can you find the perimeter if you know area of a square?

For a square yes. If square root the area, you will get the length of a side. Times this by 4 to get the perimeter. E.g. Area=64cm2 64(square rooted)=8cm 8 X 4=32cm Perimeter=32cm

### Is area always more or equal to the perimeter in a square?

The area of a square is equal to twice the square's perimeter.

### How can you find the area of a square if you know the perimeter?

multiply the widht time s the length

### How do you find the area of a yard using the perimeter in square feet?

You can't only using the perimeter. You have to know length and width.

### How do you find the perimeter when you know the area?

There is no possible way to. You can only add up all the sides to get the perimeter.---It is not impossible. You can get the perimeter from area very easily.First, you find the square root of the area, which will be the length of each side (assuming it is a square).Then, once you've found the length of each side, you multiply it by 4, and you should have the perimeter.

### What is the area of a perimeter with 6 inch sides?

That's oddly worded. You can't find the area of a perimeter. Either way, we need to know how many sides there are. A square with 6-inch sideshas a perimeter of 24 inches and an area of 36 square inches.

### How can you find the length of a side of a square if you know the perimeter?

If a square has sides of length x, it's perimeter must be 4x. Therefore the length of one of those sides is the perimeter divided by 4. Square this number (multiply it by itself) to get the area of the square.

### How do you find the perimeter using area?

Depending on the figure given you can find the area from the perimeter For example- If you have a square with a perimeter of 24, you divide 24 by 4 because all the sides of a square are congruent. In turn you will 6 as each side of the square The formula for the area of a square is side2 so you get 62 which is 36. The area is 36

### How do you know the perimeter of a square and you want to determine its area Explain how you can calculate the area?

For a square, the area is always 1/4 of the perimeter squared. Or one side squared.

### How do you find the optimal dimensions of a rectangle if you know the area?

Assuming that you want to minimise the perimeter, then use a square. Its side length is, of course, given by the square root of the area.

### How do you find the perimeter of a square when only the area is given?

Since you know that a square has four congruent sides, you know that the area is s2. If you want to find the length of one side, take the square root of both sides, so you're left with s= the square root of the area. A square has 4 sides, so to find the perimeter (4s = P), multiply both sides by 4. So you end up with this: P= 4A1/2 where P is the perimeter, A is the area, and the 1/2 means the square root. In simple terms, take the square root and multiply by four.
