Question

A rectangular park is 45 m long and 30 m wide. Find its length of boundary​

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:

150m

Step-by-step explanation:

length (long) = 45m

breadth( wide) = 30m

perimeter( length of boundary)

= 2×(L+B)

= 2×(45+30)m

= 2×75m

= 150m
