The height of a right trapezoid is \(4\, \mathrm{cm}\).
The length of the longer base is \(7\, \mathrm{cm}\)
and the angle between this base and the leg of the trapezoid is
\(52^{\circ }\). Find
the perimeter of the trapezoid and round to the nearest centimeters. See the picture with a right trapezoid.
\(20\, \mathrm{cm}\)
\(18\, \mathrm{cm}\)
\(19\, \mathrm{cm}\)
\(21\, \mathrm{cm}\)
