A:

 

Given space 3 space horses space are space tethered space with space 7 space straight m space long space ropes space at space three space corners space of space increment ABC Here space radius space of space sectors comma space straight r space equals space 7 space straight m  Area space of space the space plot space which space can space be space gazed equals fraction numerator straight x to the power of degree over denominator 360 degree end fraction cross times πr squared plus fraction numerator straight y to the power of degree over denominator 360 degree end fraction cross times πr squared plus fraction numerator straight z to the power of degree over denominator 360 degree end fraction cross times πr squared equals fraction numerator πr squared over denominator 360 degree end fraction cross times open square brackets straight x to the power of degree plus straight y to the power of degree plus straight z to the power of degree close square brackets equals fraction numerator πr squared over denominator 360 degree end fraction cross times 180 to the power of degree equals 1 half cross times 22 over 7 cross times 7 cross times 7 equals 77 straight m squared
