Answer 2

Answer:

$= 2900 {m}^{2}$

Step-by-step explanation:

side of square park. =100m

width of road. =5m

Area of square park = side ×side

= 100m × 100m

=10000 sq. m

side of park except road =100m -5m -5m

=100m-10m

=90m

so ,

Area of park except road = side ×side

=90m ×90m

=8100 sq. m

Hence,

Area of road = (10000 - 8100) sq. m

= 2900 sq. m

Ans: 2900 sq. m
