Question

find the area of the following polygon​

Answer 1

Answer:

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:

area of polygon = 381cm²

Step-by-step explanation:

area of polygon = area of trapezium (1) + area of rectangle (2) + area of trapezium (3)

=> area of polygon = { (1/2)(12+25)(6) + (25×8) + (1/2)(10+25)(4) }

=> area of polygon = (37)(3) + (200) + (35)(2)

=> area of polygon = 111 + 200 + 70

=> area of polygon = 381cm²
