Question

length of a rectangular field is 40 m and breadth 25 M .with 2.5mt Path is all around it. find the area of the park​

Answer 1

Answer:

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

Hence, this is the answer.

Answer 2

Answer:

Length = 24.5 m

Breadth = 18 m

∴ Area of the rectangle = Length × Breadth

= 24.5 m × 18 m

= 441 m2

(ii) Length = 12.5 m

Breadth = 8 dm = (8 × 10) = 80 cm = 0.8 m [since 1 dm = 10 cm and 1 m = 100 cm]

∴ Area of the rectangle = Length × Breadth

= 12.5 m × 0.8 m

= 10 m2
