Объяснение:

△ABD - равнобедренный т.к. AB = BD по условию,

Пусть BH - высота, она проведена к основанию,

Высота равнобедренного треугольника, проведённая к его основанию является так же и медианой.

⇒ BH - медиана;

AH = HD т.к. H - основание медианы;

AH = AD:2 = 6см:2 = 3см.

△AHB - прямоугольный т.к. ∠AHB = 90°,

Квадрат гипотенузы равен сумме квадратов катетов (т. Пифагора).

AB² = AH²+BH²;

BH² = AB²-AH²;

BH² = 5²-3²;

BH² = 25-9 = 16 = 4²;

BH = 4 см.

Площадь параллелограмма равна произведению его высоты на сторону, к которой она проведена.

BH - высота параллелограмма ABCD, проведённая к стороне AD;

S = BH·AD;

S = 4см·6см = 24см².
