Question

fie abcd un parallelogram h1= d(A, BC), h2= d(B, CD) si A aria paralelogramului.
a) AB=?, BC=15, h1=12, h2=10 A=?
b)AB=? BC=? h1=7, h2= 10,5 A= 210

Answer 1

a) A=h1*BC=12*15
    A=h2*CD=h2*AB=10*AB⇒12*15=10*AB⇒AB=12*15/10=18
    A=12*15=180
b)A=h1*BC⇒210=7*BC⇒BC=210/7=30
   A=h2*CD=h2*AB⇒210=10,5*AB⇒AB=210/10,5=20
