Question

a horse is tethered to one corner of a rectangular field measuring 60 m by 40m.The rope is 21 m long .How much area can the horse graze? ​

Answer 1

Answer:

we will find area of circle taking r =14m,area of sector= 90degree/360degree * 22/7 * 14*14=154 sq.m

Answer 2

Answer:

Step-by-step explanation:

The horse grazes as much as it can..it covers an area...that it forms a sector... Considering the rope measurement as radius i.e 21 m

And rectangle corner will form a 90 degree...so area of sector = teeta/360 ×πr sq...

90/360×22/7×21×21

1/4×22×3×21

1×11×3×21/2

33×21/2

693/2

346.5
