And also it can not be expressed as terminating decimal or repeating decimal

Example of the irrational number is given below.

$\sqrt{8}= 2.82842$

$\pi = 3.14285..$

$\sqrt{3}= 2.82842$

Area of rectangle= Length×breadth

Area of rectangle=12 cm×10 cm

Area of rectangle=120 cm²

Hence, the area of the rectangle is 120 cm².
