Question

a rectangular park is 45m long and 30 m wide, a path 2.15m wide is constructed outside of the park find the perimeter of the path​

Answer 1

Area of the park without path = 45 m × 30 m

= 1350 m²

Length of the path with park = 45 + ( 2.15 × 2)

= 45 + 4.3

= 49.3 m

Breadth of the path with park = 30 + (2.15 × 2)

= 30 + 4.3

= 34.3 m

Hence,

Perimeter of the path = 2 (49.3 + 34.3) m

= 2 × 83.6 m

= 167.2 m

Answer 2

Answer:

20 m

Step-by-step explanation:

Length of park including path= 45+(2×2.5)m

= 50 m

Breadth of park including path= 30+(2×2.5)m

= 35 m

Perimeter of park including path= 2(50+35)m

= 170 m

Perimeter of park excluding path=2(45+30)m

= 150 m

Perimeter of path= (170-150)m

= 20 m
