Question

A rectangle park is 45 m long and 30 m wide. A path 5 m wide is

constructed outside the park. Find the area of the path.​

Answer 1

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

Question :

• A rectangle park is 45 m long and 30 m wide. A path 5 m wide is constructed outside the park. Find the area of the path.

Answer :

Given:

• A rectangular park with length = 45m
• Breadth= 30m
• And path = 5m

To Find :

☞ Area of the path.

Solution :

➠ Area of a rectangular park = l×b

= 45×30

$\color{blue} = 1350 {m}^{2}$

➠ Area of park with path = (40+5+5) × (30+5+5)

= 55×40

$\color{indigo}= 2200 {m}^{2}$

» Therefore Area of path = 2200 - 1350

$\color{cyan} \boxed{ \colorbox{black}{ = 850m²\color{red}★}}$

» Hence, the required area is 850m².
