Question

# A rectangular 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.

Solution

## Area of park $$=l \times b= 45 \times 30=1350\ cm^2$$Area of park with path is $$=45+2.5+2.5 \times 30+2.5+2.5 = 1750\ cm^2$$Therefore,Area of path $$=$$ Area of park with path $$-$$ Area of rectangular park             $$= 1750-1350=400\ cm^2$$Hence, this is the answer.Mathematics
