An oblong piece of ground measures 19m 2.5dm by 12m 5dm.From center of each side of the ground, a path 2m wide goesacross to the center of the opposite side.What is the area of the path ?

A. 59.5 m2

B. 54 m2

C. 78.54 m2

D. 34 m2

Answer : C. 78.54 m2

Explanation:

Area of path horizontal = 20 * 192.5
3850 dm2
Area of path vertical = 20 * 125
2500 dm2
Since center path is covered twice so total area,
= (3850 + 2500) – (20 * 20)
= 5950 dm2
Total cost = 1.32 * 59.5 m2
78.54 m2
