Answer 1

triangle 1/2 x base x height

parallellogram =base x height

trapezium= 1/2 (sum of parallel sides) × (perpendicular distance between them)

rhombus = Area= (d1*d2)/2 where d1 is the diagonal and d2 is the other diagonal

pentagon = The Area of a Pentagon Formula is, A = 5/2 x sa

Where,

s is the side of the pentagon.

a is the apothem length.
