squares of a fixed size. The standard unit of area is the square metre ** (m2) **given
by the In the

**International System of Units (SI).**

## Area of Plane Shapes

### Area of Rectangle

Area of rectangle is the multiplication of the length and width of the rectangle.

*A= L x W*

### Area of Square

The area of square is the square of the length of a side.

*A= a**Â˛*

### Area of a Triangle

Area of a triangle is the half of the product of base and height.

*A= (b x h)/2*

### Area of Trapezoid

The area of trapezoid is given by:

*A=h.[(a + b)/2]*

Where, ** a **and

**are the two bases of trapezoid,**

*b***is the height.**

*h*### Area of Parallelogram

Area of parallelogram is the multiplication of the base and height of parallelogram.

*A= b x h*

### Area of Circle

The area of circle is the product of **Ď€ **to the square of radius.

*A = Ď€r**Â˛*

### Area of Ellipse
