Question

I kindly request to all the brainly users please solve the que.no.9 if you can

Answer 1

Each cow will graze 1 quadrant

4 quadrant = 1circle

r = 1/2 square side

r = 1/2 × 70 = 35m

Area of square = side × side

= 70 × 70


$= 4900m {}^{2}$

$area \: of \: circle = \pi \: r {}^{2}$

= 22/7 × 35 ×35

= 110 × 35

$= 3850m {}^{2}$

area ungrazed = area of square - area grazed

4900 - 3850

=
$1050m {}^{2}$
