Answer:
C
Step-by-step explanation:
A heptagon is a polygon with 7 triangles. (a)
Thus, The area (A) will be = 7a
[tex]The \ area \ of \ \ triangle \ = (1/2) \times b \times h[/tex]
where;
b = base
h = height
So;
[tex]7a = \dfrac{1}{2}(bh)[/tex]
where;
b = 22.15 unit and h = 23 unit
∴
[tex]A = \dfrac{7 \times b \times h}{2} \\ \\ A = \dfrac{7 \times 22.15 \times 23}{2} \\ \\ A = 1783.07 \ sq. units \\ \\ A \simeq 1783 \ sq. units \\ \\[/tex]
