Question

Small Basic Project (Area and Perimeter of
shapes)​

Answer 1

Answer:

Area

Area is the region bounded by the shape of an object. The space covered by the figure or any geometric shapes is the area of the shape. The area of all the shapes depends upon its dimensions and properties. Different shapes have different areas. The area of the square is different from the area of kite.

If two objects have a similar shape then its not necessary that area covered by them will be equal unless and until the dimensions of both the shapes are also equal. Suppose, there is two rectangle box, who has the length as L1 and L2 and breadth as B1 and B2. So the areas of both the rectangular box say, A1 and A2 will be equal only if L1=L2 and B1=B2.

Perimeter

Perimeter of a shape is defined as the total distance around the shape. Basically, its the length of any shape if it is expanded in a linear form. The perimeter of different shapes can match in length with each other depending upon their dimensions.

For example, if a circle is made of a metal wire of length L, then the same wire we can use to construct a square, whose sides are equal in length.

Area and Perimeter Formulas For all Shapes

There are many types of Shapes. The most common ones are Square, Triangle, Rectangle, Circle etc. To know the area and perimeter of all these, we need different formulas.

Perimeter  and Area of a Rectangle

A rectangle is a figure/shape with opposite sides equal and all angles equal to 90 degrees. The area of the rectangle is the space covered by it in an XY plane.



Perimeter of a Rectangle = 2(a+b)

Area of Rectangle = a × b
