In the adjoining fig. `square` ABCD is a trapezium AB || CD and its area is 33 cm2. From the information given in the figure find the lengths of all sides of the `square` ABCD. Fill in the empty boxes to get the solution.

Solution: `square` ABCD is a trapezium.

AB || CD

`"A"(square "ABCD") = 1/2 ("AB" + "CD") xx`______

33 = `1/2 ("x" + 2"x" + 1) xx `______

∴ ______ = (3x + 1) × ______

∴ 3x2 +______ − ______ = 0

∴ 3x(______) + 10(______) = 0

∴ (3x + 10) (______) = 0

∴ (3x + 10) = 0 or ______ = 0

∴ x = `-10/3` or x = ______

But length is never negative.

∴ `"x" ≠ -10/3`

∴ x = ______

AB = ______, CD = ______, AD = BC = ______
