Question

A rectangle has length 18 cm and breadth 8cm .If it's length is changed bi 2 upon 3times and the breadth by 3 upon 2 times , than that what is the changes in its area ?​

Answer 1

Answer:

There is no change in area .

Step-by-step explanation:

Given,

        A rectangle has length= 18 cm

       A rectangle has Breadth= 8 cm

Area of the Rectangle =Length ×Breadth

                                     $=18 \cdot 8\\ \\ =144 {cm}^2$

After change,

        It's length is changed bi 2 upon 3 times

        Length will be=$\frac{2}{3}\cdot 18=2\cdot6=12 cm$

       Its breadth by 3 upon 2 times

Breadth will be =$\frac{3}{2}\cdot 8=3 \cdot 4=12$

Area after change =$12 \cdot 12=144cm^2$

Change in area =$144-144=0$
