Question

find the area of the polygon​

Answer 1

Step-by-step explanation:

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

Answer 2

Answer:the correct answer is 410cm sq.

2height of trapezium =total height of the figure - length of the rectangle

=>2h = 50-40

=>2h=10

=>h=10/2

=>h= 5cm

Required area = area of two equal trapezium + area of rectangle

=2*1/2*(sum of parallel sides) *h+l*b

=(8+10)*5+40*8

=18*5+320

=90+320

=410 cm sq.

area of polygon =410cm sq
