How do you find the perimeter of a rectangle when only the area is given?
You cannot find the perimeter unless the rectangle is a regular rectangle (a square) in which case the perimeter is 4 times the square root of the area. With just the area the shape of the rectangle could be any number of shapes with different perimeter, for example, imagine 6 square units 1cm by 1cm arranged in a 1*6 configuration to give a long thin rectangle, the perimeter would be 6+6+1+1=14cm, the same 6 arranged in a 3*2 rectangle would have the same area, but a perimeter of 3+3+2+2=10cm, for this reason a rectangle's perimeter cannot be determined from the area alone.
How do you find diagonal of rectangle when perimeter and width are known?
Length = (1/2 of perimeter) minus (Width) Diagonal = square root of [ (Length)2 + (Width)2 ]
The vertices of a quadrilateral are (4 15) (7 21) (26 4) and (29 10). What is the approximate perimeter of the quadrilateral?
The sides of the rectangle are 3 times square root of 5 and 5 times square root of 26 The perimeter of the quadrilateral is approximately 64 units
What is the perimeter of a square with the area 25 square ft?
perimeter of a square = 4 * root of the area. Perimeter = 4 * root 25 = 4 * 5 = 20 ft
What is the perimeter if the area is 9 sq cm?
Depends on the shape. A square's perimeter would be 4 root 9 ie 12 cm, but you could have a 9 x 1 rectangle which would have a perimeter of 20 cm etc etc
What is the perimeter of a rectange if the areas 405 yd?
The perimeter of a rectangle cannot be calculated by just knowing the area unless the rectangle is a square. In which case the perimeter will be 4 x square root of the area.
What is the perimeter of the rectangle that is 0.9 square units?
There is no single answer to that The rectangle could be 0.9 by 1, giving a perimeter of 2x(0.9+1)=3.8 Or it could be 0.45 by 2, giving it a perimeter of 2x(0.45+2)=4.9 The minimum perimeter is when it is a square. The square root of 0.9 is approx 0.94868, so the perimeter would be approx 3.7947

If you have the diagonal and with of a rectangle how do you find the Perimeter?
Square the diagonal and take away the square of width, this gives you the square of the other side. Add the square root of the two sides and multiply by two.
There are three shapes circle rectangle and square which one has least perimeter?
For a given area a circle has least perimeter. eg Let area = 100 sq cms. For the square or rectangle the perimeter = 40 cms For the circle the radius is square root of 100/3.1416 = 5.64 and the circumference = 2 x radius x 3.1416 = 35.44 cms
The vertices of a quadrilateral are (4 15) (7 21) (26 4) and (29 10). What is the approximate perimeter of the quadrilateral?
The sides of the rectangle are 3 times square root of 5 and 5 times square root of 26 The perimeter of the quadrilateral is approximately 64 units
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.
What is the perimeter of a square with the area 25 square ft?
perimeter of a square = 4 * root of the area. Perimeter = 4 * root 25 = 4 * 5 = 20 ft
How do you turn square feet into a perimeter?
To find the perimeter of a shape given the area in square feet, you need to know the dimensions of the shape. If it's a square or rectangle, you can calculate the perimeter by finding the square root of the area to get the side length, and then multiply that by 4 for a square or 2 times the sum of the length and width for a rectangle. If it's a different shape, you will need additional information to determine the perimeter.
What are the possible perimetersof a rectangle with an area of 48 square yards?
Minimum is when the figure is a square, in this case the perimeters 4 times the square root of 48. There is no maximum, i.e., you can make the perimeter as large as you like.
What is the perimeter if the area is 9 sq cm?
Depends on the shape. A square's perimeter would be 4 root 9 ie 12 cm, but you could have a 9 x 1 rectangle which would have a perimeter of 20 cm etc etc
