Geometry Edge of Rectangular

Introduction to Geometry edge of rectangular:

Rectangular shape is one of the geometry two dimensional objects. Geom`etry edge of rectangular properties are the crossed quadrilateral which consists of two opposite sides of a rectangle along with the two diagonals. Its angles are not right angles. Opposite sides are parallel and congruent . The diagonal bisect each other The diagonals are congruent. A four -sided plane figure with four right angles. Understanding Volume of a Rectangular Prism Formula is always challenging for me but thanks to all math help websites to help me out.

Basic Concepts of Geometry Edge of Rectangular:

Geometry edge of rectangular:

Each and every object should have edges. Two edges make the angle of geometry object.And also edges to make the corners and vertices of object .Rectangle have  four  edges and also have four vertices or corners .Each corner make the angle of 90degree.

From this diagram:

AB, BD, DC, AC are edges of the rectangle.

AB edge is parallel to CD edge

AC edge is parallel to BD edge

AB || CD, AC || BD (opposite sides are equal in rectangle)

Each edge should make the angles are


Please express your views of this topic how many edges does a rectangular prism have by commenting on blog.

Area and Perimeter of the Geometry Edge of Rectangular:

Area and perimeter:

Area of rectangle= Length * Width

Perimeter of the rectangle=2(Length + Width)

Both area and perimeter are depends on the rectangle edges.

A rectangle has two Length edges and two width edges.

Length edges are AB, CD

Width edges are BD, AC

Two length edges are equal AB=CD

Two width edges are equal BD=AC

Example problems in Geometry edge of rectangular:

1.From given diagram Find the area and perimeter of the rectangle  and name of the rectangular edges?

Solution:

Given data PQRS is closed rectangle

PQ= 13cm(PQ||SRsO P)

PQ=SR=13

QR=5.5cm(QR||PS)

So QR=PS=5.5

Length   of the rectangle=13

Width of the rectangle =5.5

Finding the area:

(1  )Area of the rectangle=Length x Width

= 13x5.5

Area =71.5cm2

(2) Finding the perimeter:

Perimeter of the rectangle=2( L+W)

=2(13+5.5)

=2(18.5)

=37cm

Perimeter=37

(3)Finding the name of the edges:

From given diagram edges are PQ,QR,RS,SP

Volume of rectangular prism

-->Let me first introduce you the topic which i have chosen today, it is called Volume of a rectangular prism. Lets discuss on how to calculate volume of a rectangular prism.

Do you know what is a rectangular prism? We have discussed on what is a rectangle but now let me give you an introduction to rectangular prism before i go ahead with volume of rectangular prism.

-->
Rectangular Prism:- It is the three dimension geometrical figure. It has three dimensional length, width and height. To find the volume of a rectangular prism you need to know its length, width and height. Look at the figure shown above. Below we have the formula to find the volume of a rectangular prism with an example.

The formula to find the volume of a rectangular prism is L*W*H now lets solve a problem below.

Example:-

Find the volume of a rectangular prism whose width = 5cm, height = 6cm, Length = 9cm

Solution:

Given: Width = 5cm, height = 6cm, Length= 9cm.

Formula for volume of rectangular prism:
Volume = L × W × H
=9 × 5 × 6
= 45 × 6
=270cm3

Work on different problems as similar as the above mentioned example. Let me know how informative was this post. :-)
