The perimeter of the polygon is 76ft and Area is 338 sq.ft, the correct option is A.
What is a Polygon?
A polygon is a closed structure with 3 or more than 3 sides.
The given polygon has 4 sides, so it is a quadrilateral
To find the area of the polygon, it can be divided into a rectangle and a triangle as shown
Area of Rectangle = Length * Width
Area of Triangle = (1/2) * base * height
Area of Rectangle = 15 *18
Area of Rectangle = 270 sq.ft
Area of Triangle = (1/2) * 8 *17
Area of Triangle = 4 * 17
Area of Triangle = 68 sq.ft
Therefore, the total area = 68 +270 = 338 sq.ft.
Perimeter of a polygon is equal to sum of all the sides
= ( 15+18+17+18+8)
= 76 ft.
