The length of one side is L+=+1+%2B+sqrt%282%29
The area of a square is given by the L%5E2
Area+=+%281%2Bsqrt%282%29%29%5E2
Area+=+%281%2Bsqrt%282%29%29%281%2Bsqrt%282%29%29
Area+=+1%2A1+%2B+1%2Asqrt%282%29+%2B+sqrt%282%29%2A1+%2B+%28sqrt%282%29%29%5E2+
Area+=+1+%2B+2%2Asqrt%282%29+%2B+2
Area+=+3+%2B+2%2Asqrt%282%29

Area of square = (1 + sqrt2)^2
= 1^1 + 2.1.sqrt2 + (sqrt2)^2
=1 + 2sqrt2 + 2
= (3 + 2sqrt2) sq. units
