Formula of diagonal of quadrilateral
If we suppose the length of a square is L, then the length of the diagonal = L √2. Area of a square = L²
If we suppose the length of a square is L, then the length of the diagonal = L √2. Area of a square = L131
If we suppose the length of a square is L, then the length of the diagonal = L √2. Area of a square = L132
If we suppose the length of a square is L, then the length of the diagonal = L √2. Area of a square = L133
