Answer» Answer: 3 km Step-by-step EXPLANATION: LET us name the given parallelogram, ABCD. Given: AB = 6 km Area of the parallelogram ABCD = 18 km² To find: AC [HEIGHT of the parallelogram $(h)$ ] Solution: AB = CD (∵ Opposite sides of a parallelogram are EQUAL) ∴ Base $(b)$ = 6 km. Area of the parallelogram ABCD = $bh$ $18km^2=CD\times AC$ $18km^2=6h$ $h=\frac{18}{6}$ $h=3km$ ∴ The height of the parallelogram is 3 km.
