Given,

Radius (r) = 25 cm

Sector angle (θ) = 115°

Since there are two blades,

The total area of the sector made by wiper,

 = 2 \times ( \frac{θ}{360} ) \times \pi {r}^{2}

 = 2 \times ( \frac{115}{360} ) \times ( \frac{22}{7} ) \times  {25}^{2}

 = 2 \times  \frac{158125}{252}   \:  \: {cm}^{2}

 =  \frac{158125}{126}  \:  \:  {cm}^{2}

 = 1254.96 \:  \:  {cm}^{2}
