IF the semicircle is on the 58m end then:
L=2*116+3.14*58
L=232+3.14*58
L=232+182.12=414.12 m. ans. for the length.
A=58*114+3.14(58/2)^2
A=6,612+3.14(29)^2
A=6,612+3.14*841
A=6,612+2,640.74
A=9,252.74 m^2. ans.
--------------------------
IF the semicircircle is on the 116m end then just replace the 58 by 116.
