What is the area if the perimeter is 40?
So in order to find area of a square from it’s perimeter, square perimeter value and divided it by 16. So if perimeter is 40 cm, it’s area is 40×40/16 = 100 cm^2.
How do you find the area from the perimeter?
What is its area? Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area. In this example, 14 ÷ 4 = 3.5.
How do you find the perimeter from the area of a square?
Perimeter of Square Using Area of Square
- Step 1: Note down the area of square.
- Step 2: Calculate the side length using the area, Side = √area.
- Step 3: Multiply this obtained value of side length, (√area) by 4 and express the answer in units, Perimeter = (√area) × 4 = 4√area units.
How do you convert square Metres to perimeter?
Multiply the side length by 4 to find the perimeter. Take the side length s you just calculated and plug it into the perimeter formula, P = 4s. The result will be the perimeter of your square!
What is the perimeter of a square meter?
36.8 meters
Perimeter of the square = 36.8 meters.
What are the formulas for area and perimeter?

Is the number 40 a perfect square?
A: No, the number 40 is not a perfect square. A perfect square is a number that can be expressed as the product of two equal integers. The only way to accurately calculate if a number is a perfect square is to find the factors.
What is the formula for finding the perimeter?
Write down the basic formula for finding the perimeter of a rectangle. This formula will help guide you as you calculate the perimeter of your own rectangle. The basic formula is: P = 2 * (l + w). Perimeter is always the total distance around the outside edge of any shape, whether it is simple or compound.
How to find perimeter formula?
The area of a rectangle is a measurement of the two-dimensional space within the rectangle,or the number of square units within the rectangle.
How to find the perimeter of a square?
– The relationship between area and perimeter of a square is that perimeter is 4 4 times the square root of the area. – To get the perimeter from the area for a square, multiply the square root of the area times 4 4. – Perimeter is always measured in linear units, which is derived from the area’s square units. – The perimeter of a square with an area of 2,025 m2 2,025 m 2 is 180 m 180 m, because the perimeter, P P, is 4√2,025 m2 4 2,025 m
