** Area of Plane Shapes -> In Geometry,** the dimensions such as length, width of any geometric structure gives us important information about the structure’s area, perimeter etc. This data and measurements are very useful in our daily life as it helps us calculate things like fencing for our back-yard, area of the space occupied etc.

Let’s look at the formulas to calculate these measurements!

**Triangles:**

**Example:**

Find the area of a triangle whose base=10 and height=5. Find perimeter if other two sides of triangle are 4 and 6.

** Area of ****Rectangle: **

**Example:**

Find the area and perimeter of rectangle with length=12 and width=8.

** Area=length *width** **-> **A=12*8 **->** **A=96**

** Perimeter=2l+2w ->** P= (2*12)+(2*8)

** ->** P=24+16 **->** **P=40**

**Area of Square:**

**Area of Circle:**

**Example:** Find the area and circumference of circle with radius=3

** Area= πr ^{2 =>}**

^{ }A= (3.14)*(3

^{2})=

**28.26**

** Circumference=2πr => **C=2*(3.14)*(3) **=>** **C=18.84**
