A rhombus shaped field has green grass for is com to graze . lf each side of the rhombus is |
|
Answer» Let ABCD is a rhombus and length of each side is 30Length of diagonal AC is 48FromΔ ABC,Let AB =a =30AC = b =48BC = c = 30Now s = (a+b+c)/2=>s = (30+48+30)/2=> s = 108/2=> s = 54 mNow area ofΔ ABC =√{s*(s-a)*(s-b)*(s-c)} =√{54*(54-30)*(54-48)*(54-30)} =√{54*24*6*24} =√{9*6*24*6*24} = 3*6*24 = 432 m2Area of rhombus ABCD = 2* area ofΔ ABC (sincearea ofΔ ABC =area ofΔ ACD) = 2* 432 = 864 m2Now area of grash for 18 cows = 864 m2Soarea of grash for 1 cows = 864/18 m2 = 48 m2 |
