Question

A rectangular park is 40m by 30m. A path 5m wide is build all around outside it. Find the cost of constructing the path at Rs 400 per sq m.​

Answer 1

Step-by-step explanation:

Area of park =l×b=45×30=1350 cm

2

Area of park with path is =45+2.5+2.5×30+2.5+2.5=1750 cm

2

Therefore,

Area of path = Area of park with path − Area of rectangular park

=1750−1350=400 cm

2

Answer 2

Answer:

Area of park = l×b = 40×30 =1200m²

Area Of park With path = 40 + 5 × 5 + 30 + 5 + 5 = 1585m²

Therefore,

Area of path = Area of path with park - Area of park

= 1585 - 1200 = 385m²
