What is the perimeter of a 2x4 rectangle? To find the perimeter of, or distance around, a 2x4 rectangle, add all four sides. The perimeter is 2 + 4 + 2 + 4 = 12 units. How do you find the perimeter and area of a rectangle? The formula to calculate the perimeter of a rectangle...
In summary, the formula to find the area of a sector in a circle is A = (πr^2θ)/360, where θ is the central angle in degrees. If θ is in radians, the formula becomes A = (r^2θ)/2. The sector area is simply a fraction of the total area of the circle. ...
The area of a rectangle is the space occupied within the boundary of the rectangle. It is calculated by finding the product of the length and breadth (width) of the rectangle and is expressed in square units.
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
Example 3:Find the area of a square whose diagonal is measured is 4 cm. Solution: Given: Side, d = 4 cm We know that the formula to find the area of a square when the diagonal, d, is given is d2÷2 square units. Substituting the diagonal value, we get: ...

We have to find the formula for the surface area of a box: Firstly we will form the diagram a box as follows: Here we have taken Height $h=BE$ Length $l=AB$ Width $w=BC$ Now as we can see that the box has six faces all are in rectangle shape. ...
Area of a CircleCircles can be witnessed from micro to macro-objects around us. For example, our Earth is a flat circle; the moon is a gigantic circle; your dog might be playing with a circular ball, and much more. A circle is a two-dimensional shape whose locus is equidistant from ...
In order to find the total space enclosed by the sector, we use thearea of a sectorformula. The area of a sector can be calculated using the following formulas, Area of a Sector of Circle = (θ/360º) ×πr2, where, θ is the sector angle subtended by the arc at the center, ...
