Question

Suraj has a rectangular meadow whose length is 3.5m and breadth is 2.8 m .If he tethers a cow in the middle of the longer side, what is the area cow can graze?​

Answer 1

Answer:

4.8125m²

hope it works

Answer 2

$\underline{\blue{ Dimensions\:of \:a \: rectangular \: meadow :}}$

$Length (l) = 3.5 \: m$

$Breadth (b) = 2.8 \:m$

/* According to the problem given */

If Suraj tethers a cow in the middle of the longer side then Area of the cow graze is equal to semicircle area .

$Radius \: of \: the \: Semicircle(r) = \frac{l}{2}$

$= \frac{3.5}{2}$

$Grazing \: area = Area \:of \: the \: semicircle$

$= \frac{1}{2} \times \pi r^{2}$

$= \frac{1}{2} \times \frac{22}{7} \times \Big(\frac{3.5}{2}\Big)^{2}$

$= \frac{269.5}{56}$

$= 4.8125 \: m^{2}$

Therefore.,

$\red{ Grazing \: area }\green {= 4.8125 \: m^{2}}$
