Question

A rectangle park is 45 m long and 30 m wide. A path 2.5 m wide is constructed outside the park. Find the area of the path​

Answer 1

Answer:

Area of park=l×b=45×30=1350m²

Area of park with path is

=45+2.5+2.5×30+2.5+2.5

=1750cm²

Therefore,

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

ㅤㅤㅤㅤ =1750-1350

ㅤㅤㅤㅤㅤ=400 cm²

Answer 2

Length of the rectangular park = 45 m

Breadth of the park = 30 m

Area of the park = l × 6 = 45m × 30m = 1350 m2

Length of the park including the path = 45 m + 2 × 2.5 m = 50 m

Breadth of the park including the path = 30 m + 2 × 2.5 m = 30m + 5m = 35m

Area of the park including the path = 50 m × 35 m = 1750 m2

Area of the path = 1750 m2 – 1350 m2 = 400 m2

Hence, the required area = 400 m2.
