Question

the side of a square is increased by 10%.find the increase in area.​

Answer 1

Answer:

A 10% increase is equivalent to 1.1 times of its current value.

Step-by-step explanation:

Reason: 10% increase = 100 + 10/100 = 110/100 = 1.1 times increase.

Now the area of a square is directly proportional to the square of the side length.

Since the square of 1.1 is 1.21, we can say that the area of the square will become 1.21 times its original value… meaning an increase by 21 percent (using the logic mentioned above).

Thus we conclude that if each side of a square is increased by 10%, then the area of the square will increase by 21%.
