What is the area of a square with the dimension of 1+square root of 2?

I'm thinking 3+2*square root of 2?

*=times

Right!

Thank you!

To find the area of a square, you need to square the length of one of its sides. In this case, the side length of the square is 1 + √2.

To calculate the area, you need to square this length.

(1 + √2) * (1 + √2) = 1 + 2√2 + √2 + 2 = 3 + 3√2.

Therefore, the area of the square with a side length of 1 + √2 is 3 + 3√2.
