Question

A cow is tied on the corner of a rectangular field of size 30 m ×20 m by a 28m long rope. The area of the region, that she can graze, is$(use \pi =\frac{ 22}{ 7} )$ :

• A. 400 sqcm
• B. 576 sqcm
• C. 616 sqcm
• D. 700 sqcm

Answer 1

Answer:

C. 616 sqcm

Given Radius, r= 28 =length of rope
