Q. What is the area of a rectangle if the length is twice the width?
Let the length of the rectangle be L and the width be W. But we know that the perimeter is 36. Now we will calculate the area: ==> A = L * W = 12* 6 = 72 square feet.
Q. What is the length and width of a rectangle if the perimeter is 36?
Expert Answers Hover for more information. The dimensions of a rectangle with perimeter 36 cm have to be determined that maximize the area without using calculus. The length of the required rectangle has a length equal to 9 and the width is 18 – 9 = 9.
Q. How do you find the length and width of a rectangle when given the perimeter and ratio?
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
Q. What is the perimeter of a rectangle if the length is twice its breadth?
Perimeter of the field is given as Perimeter = 2(Length + Breadth) and it is 150 cm.
Q. What is the area of the perimeter is 36?
If perimeter = 36, for a square each side length would be 36/4=9 units. So area is 9 x 9 =81 squared units.
Q. What is length and width?
Length is the distance from one end to the other end of an object, while the width is the distance from side to side. Length is a type of measurement that shows how tall or long an object is. Width is a type of measurement that shows how wide an object is.
Q. How do you find the length of a rectangle if you know the area?
To find Length or Breadth when Area of a Rectangle is given
- When we need to find length of a rectangle we need to divide area by breadth.
- Length of a rectangle = Area ÷ breadth.
- ℓ = A ÷ b.
- Similarly, when we need to find breadth of a rectangle we need to divide area by length.
- Breadth of a rectangle = Area ÷ length.
Q. How do you find the perimeter given the area?
To get the perimeter from the area for a square, multiply the square root of the area times 4 . Perimeter is always measured in linear units, which is derived from the area’s square units.
Q. What is the relationship between perimeter and area?
What is the difference between the perimeter and area of a shape? The perimeter is the sum of all the side lengths of a shape. The area is the amount of two dimensional space a shape occupies.
Q. What does πr2 mean?
Area of a Circle. The area of a circle is given by the following formula: A=πr2 where r is the radius of the circle. What is a radius? It’s the distance from the center of the circle to any point on the edge of the circle. The radius will always be the same length!
Q. What will be area of the circle?
The area of a circle is pi times the radius squared (A = π r²).
Q. What is perimeter explain?
Perimeter is the distance around the edge of a shape. Learn how to find the perimeter by adding up the side lengths of various shapes.
Q. What is the symbol of perimeter?
How to find perimeter?
| Polygon name : | Perimeter Formula : |
|---|---|
| Scalene Triangle | P = a + b + c |
| Square | P = 4 x a |
| Rectangle | P = 2 ( a + b ) |
| Quadrilateral | P = a + b + c + d |
Q. How many types of perimeter are there?
Perimeter of a Rectangle = 2 (L+B) = 2 (6 cm + 4 cm) = 2 × 10 cm = 20 cm….Area and Perimeter Formula Chart.
| Geometric Shape | Perimeter Formula | Metrics |
|---|---|---|
| Parallelogram | 2(Base + Height) | |
| Triangle | a + b + c | a, b and c being the side lengths |
| Rectangle | 2(Length + Width) | |
| Square | 4a | a =Length of a side |
Q. How do we use perimeter?
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
