Question

Three horses are tethered at 3 corners of a triangular plot

having sides 20 m, 30 m, 40 m with ropes of 7 m length

each. Find the area of the plot which can be grazed by the horses. (Take π = 22/7)​

Answer:

The area of the plot which can be grazed by the horses is 77 Sq.cm

Step-by-step explanation:

We have :

Radius = 7m [Sector Radii]

A = 20m

B = 30m

C = 40m

Formula of Area  $=\frac{x^{0} }{360^{0} } (\pi r^{2} )+\frac{y^{0} }{360^{0} } (\pi r^{2} )+\frac{z^{0} }{360^{0} } (\pi r^{2} )$

Here,

R = Radius

$\pi$ = Pi [ value = $\frac{22}{7}$]

Now,

= $\frac{\pi r^{2} }{360^{0} } (180^{2} )$

= $\pi \frac{7^{2} }{2}$

= $\frac{22}{7} *\frac{49} {2}$

= $77$ Sq.Cm
