Question
A horse is placed for grazing inside a rectangular field 40m by 36m and is tethered to one corner by a rope 14m long. Over how much area can it graze.
Solution
The fig shows rectangular field ABCD at corner A, a horse is tied with rope length = 14m.
The area it can graze is represented A as shaded region= area of quadrant with (radius = length) of string
Area = `1/4`× (๐๐๐๐ ๐๐ ๐๐๐๐๐๐) = ๐๐2
`= 1/4 ×22/7 × 14 × 14`
= (22 × 7)
= 154 m2.
Area it can graze = 154m2.
