 Hello all and welcome to the session. Today the question is, a square with size 5 cm is drawn anywhere in the plane which is then enlarged about any point in the plane with the scale factor 3. What is the area of the image of the square? Now before starting the solution of the question we should know about a result and which is, area of the image is equal to k square times area of the image where k is the scale factor by which the given figure is enlarged. And this result will work out as a key idea for solving out this question. And now we will start with the solution. Given the scale factor k is equal to 3 also given side of the square is equal to 5 cm. Now we know that area of the square is equal to side into side which is 5 into 5 cm square which is further equal to 25 cm square. And also according to the formula which is given in the key idea, area of the image is equal to k square times area of the pre-image. Now we will put the values of k and the area of the pre-image here and there the value of k is 3 so it will be 3 square into area of the pre-image which is 25 cm square which is equal to 3 square is 9 into 25 which is equal to 225 cm square. Therefore, area of the image of the square is equal to 225 cm square. So this is the solution of this question. That's all for this session. Hope you all have enjoyed this session.
