Question

a cow is tethered with a rope of length 35 m at the center of the rectangular field of length 76m and breadth 60m. find the area of the land that the cow cannot graze? for 7th std challenge problem

Answer 1

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.
