The road is 2.5 meters on each side of the square, so it would form a larger square 20m x 20 m (2.5 m road + 15 m garden +2.5 m road).
The area of this larger square (20 m)(20 m)= 400 sq meters
The area of the garden (middle of larger square) is (15 m)(15 m)=225 sq meters
400 sq meters total-225 sq meters garden=175 sq meters of road
ANSWER
the area of the road is 175 sq meters.
The area of this larger square (20 m)(20 m)= 400 sq meters
The area of the garden (middle of larger square) is (15 m)(15 m)=225 sq meters
400 sq meters total-225 sq meters garden=175 sq meters of road
ANSWER
the area of the road is 175 sq meters.

area of square = 15×15
=225
length of square road = (15)+2(2.5)
=20
Area of square road =20×20
=400
we know that
area of road =Area of square road - Area of Square
= 400 - 225
= 175
