Area of the ||logram ABCD = base * height
Base AB * Height ( length of perpendicular from D to base AB) = 4 * 1.5 = 6
but this is also equal to Base BC * ( length of perpendicular from D to base BC ) = 3 * x

this implies x = 6/3 = 2.

we need to equat the area of parallelogram with base AB to base BC .

so 1.5*AB= BC*h
1.5*4= 3*h

so h = 2

S = h*AB
S = 1.5*4
S = 6cm²

S = x*BC
6 = x*3
x = 2cm
