Step-by-step explanations. it’s clear that the horse can graze an area of a sector of a circle with radius (r) 5m and an angle with a degree measure 90° [Since its a square field]
Length of the rope = 5 m
Area of the field the horse can graze = Area of the sector with θ = 90° and r = 5
= θ/360° × πr2
= 90°/360° × πr2
= 1/4 × π × (5 m)2
= 25/4 × 3.14 m2
= 19.625 m2
