Rampur Sarpanch requested one of his villager to donate a 6m wide land adjusted to his 132.8m long side of his right triangular
Ronch [10]

Answer:

Area of the remaining triangle with the villager is 1243.13 m²

Step-by-step explanation:

Triangle ABC is the triangular plot of a villager shown in the figure attached.

Sarpanch requested the villager to donate land which is 6 m wide and along the side AC which measures 132.8m.

Other sides of the plot has been given as AB = 50m and BC = 123 m.

Now area of this land before donation = \frac{1}{2}\times {\text{Height}}\times \taxt{Base}

= \frac{1}{2}\times (123)\times (50)

= 3075 square meter

After donation of the land the triangle formed is ΔDBE.

In ΔABC,

tan(ABC)=(\frac{AB}{BC})

tan(∠ABC) = \frac{50}{123}

                 = 0.4065

∠ABC = tan^{-1}(0.4065)

          = 22.12°

In ΔEFC,

tanC = \frac{EF}{CF}

0.4065 = \frac{6}{CF}

CF = \frac{6}{0.4065}

CF = 14.76 m

Since DE = AC - (CF + AG)

               = 132.8 - (2×14.76)

               = 132.8 - 29.52

               = 102.48 m

Now in ΔDBE,

sin(∠DEB) = \frac{BE}{DE}

sin(22.12) = \frac{BE}{102.48}

DB = 102.48×0.3765

     = 38.59 m

Similarly, cos(22.12) = \frac{BE}{DE}

0.9264 = \frac{BE}{102.48}

BE = 102.48×0.9264

     = 94.94m

Now area of ΔDBE = \frac{1}{2}(DB)(BE)

                                = \frac{1}{2}(38.59)(94.94)

                                = 1831.87 square meter

Area of remaining triangle with the villager = Area of ΔABC - Area of ΔDBE

= 3075 - 1831.87

= 1243.13 square meter
