Answer:
hello good morning have a good day take care
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.

Area of polygon = Area of ABCD+Area of ΔBCE+Area of ΔAFD=AB×BC+ 21 ×BC×OE+ 21
×AD×FP=12×35+ 21×10×35+ 21 ×10×35=350+420=770cm
