A rectangular grassy plot is 112 m by 78 m. It has a gravel path 2.5 m m wide all around it on the inside.Find the area of the path ?
A. 952 m²
B. 925 m²
C. 912 m²
D. 950 m²
Answer : B. 925 m²
Explanation:
Outer length of the grassy plot = 112 m
Outer breadth of the plot = 78 m
Outer area of the plot = 112 x 78
= 8736 sq m
Width of the path = 2.5 m
Inner length of the plot = 112 – (2 x 2.5)
= 107 m
Inner breadth of the plot = 78 – (2 x 2.5)
= 73 m
Inner area of the plot = 107 x 73
= 7811 sq m
Area of the path = Outer area of the plot – inner area of the plot
= 8736 – 7811
= 925 m²
