A rectangular plot measures 125 m by 78 m. It has a gravel path 3 m wide all around on the outside. Find the area of the path and the cost of gravelling it at RS. 75 per m 2 .

Question

Philoid · Accepted Answer

Given:

Length of plot = 125 m

Breadth of plot = 78 m

Therefore,

Length of plot with path = 125 + (3 + 3)

= 131 m

Breadth of plot with path = 78 + (3 + 3)

= 84 m

Now,

Length to be covered = 35 – (2.5 + 2.5)

= 30 m

Breadth to be covered = 18 – (2.5 + 2.5)

= 13 m

Area of park = Length × Breadth

= 30 m × 13 m

= 390 m²
