Question

A horse is place for grazing just inside a rectangular field of 70m by 52m and is tethered tone corner by a rope 21m long. On how much area it could graze in sq mselect one:

Answer 1

area = (theta/ 360) *πr^2

=(90/360) *π21^2

= 346.4 sq m

Answer 2

$\huge{\bf{\sf{\underline{\color{navy}{ᴀɴ}}\underline{\purple{sᴡ}}\underline{\pink{ᴇʀ}}}}}$

∴ Ar.(quadrant) = 346.5 m²

______________________________

Given :

r = 21 m

Solution :

∴ Ar.(quadrant) = ¼ x πr²

= ¼ x ²²⁄₇ x 21 x 21

= ³³ˣ²¹⁄₂

= ⁶⁹³⁄₂

∴ Ar.(quadrant) = 346.5 m²
