Question

Four cows are tethered at four corners of a square plot of side 50 m, so that they just cannot reach one another. What area will be left ungrazed? (Fig. 15.66)

Answer 1

It is given that four cows are tethered at four corner of square ABCD. We have to find the area of plot that will left ungrazed.

Let the side of square is a.

a = 25 + 25 m = 50 m

Area of square = a²
$$\begin{gathered} =50\times 50 \\ =2500m^2 \end{gathered}$$
