Asquare barn measures 40 feet on each side.
a goat is tethered outside by a rope that is
attached to one corner of the barn:

a. suppose that the length of the rope is 28 feet. on how many square meters of land is the goat able to graze? what shape is formed?

616 sq. feet and it will be a quarter circle.

Step-by-step explanation:

A square barn measures 40 feet on each side.  A goat is attached to one corner of the barn by a rope that is 28 feet long.

See the attached diagram.

Now, A is the corner where the rope is attached.

So, the area where the goat will be able to graze in the area AEF which is nothing but a quarter circle as ∠ EAF = 90°.

So, the area of the quarter circle will be sq. feet. (Answer)
