Q. A circular field has a perimeter of 660 m . A plot in the shape of a square having its vertices on the circumference is marked in the field , calculate the area of the square plot ( π = 22 7 ) Share with your friends Share 0 Varun Rawat answered this We have,perimeter of the circular field = 660 m⇒2πr = 660 radius of the circular plot⇒2 × 227 × r = 660⇒r = 105 mNow, diameter of the field = 2r = 2×105 = 210 mSo, AC = 210 mNow, we know that each angle of a square is a right angle.So, ∠ABC = 90°In ∆ABC, AC2 = AB2 + BC2 Pythagoras theorem⇒2102 = AB2 + AB2 as, length of each side of square is equal⇒2AB2 = 210⇒AB2 = 105⇒AB = 105 marea of square ABCD = AB2 = 105 m2 -3 View Full Answer
