Answer 5

nonagon has 9 sides... ok... so n will be 9... so finding the angles first.. it will be (7/9)π
= 140° for "x" and for "y" it will be (2/9)π = 40°... now use the formula to find the area of this nonagon... formula is A = (1/4)na^2 cot(π/n) = nr^2 tan(π/n)... after putting all the values and necessary calculations... we will get A ≈ 1390.91 cm²...
