Answer:
Step-by-step explanation:
Area of rectangle = l × b
Area of circle = πr²
Area of rectangle - Area of Circle = Area the cannot graze.
Given :
L = 76m
B = 60m
Length of rope = 35m (which is the radius)
Applying given measurements :
(L×B) - πr² = Answer
76×60 - (22/7)×35²
= 4560 - (22/7 × 35 ×35
=4560 - (22×5×35)
=4560 - 3850
=750sqm.
Hope you got it.pls give a thumbs up.
