Question

If the sides of a square are increased by 20%, by what percentage does the area of the square increase?

Answer 1

Assume that the side of the square is `x`.

Therefore, if we increase a side of the square, the new side length would be `1.2x`

Right? `1x` would be itself, then we increase by `0.2`, so `1.2`

Now the area:

The Old square: would be `x*x`, so `x^2`

The New square: would be `1.2x * 1.2x`, so then `1.44x^2`

Thus, the area of the square will be increased by `44%`
