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
