Question

a rhombus shaped field has grass for 18 cows. each side is 30 cm and longer diagonal is 48 cm. how much area will each cow get to graze on.

answer with method

Answer 1

hi
WKT
D1=
LET D2=X
BY PYTHAGORAS THEOREM
30^2=24^2+X^2
900=576+X^2
X^2=324
X=18

WKT
AREA OF RHOMBUS =1/2*D1*D2
                                     =1/2*18*24
                                      =18*12
                                       216M^2
NO OF COWS THAT CAN GRAZE=216/18=12
