Question

a foot path of uniform width 3 metre runs around the inside of a rectangular Park 26 metre long and 18 metre wide find the area of path also find the cost of construction of part @ rupees 450 per square metre​

Answer 1

Step-by-step explanation:

length of rectangular park = 26 m

breadth of rectangular park = 18 m

area of park = l × b

= 28 × 18

= 504 sq m (1)

length of rectangular park without footpath = 20 m

breadth of rectangular park without footpath = 10 m

area of rectangular park without footpath = l × b

= 20 × 10

= 200 sq m. (2)

area of footpath = (1) - (2)

= 504 - 200

= 304 sq m

cost of construction 450 per sq m

total cost

= 304 × 450

= 136800

total cost = Rs. 1,36,800
