Anna calculated the area of parallelogram with a base of 72
5
m and a height of 2 m. Her work is shown here.
A = One-half b h = one-half (7 and two-fifths) (2) = one-half (StartFraction 35 Over 5 EndFraction) (StartFraction 2 Over 1 EndFraction) = StartFraction 70 Over 10 EndFraction = 7 meters squared
