Answer 1

Answer:

$\color{black}\boxed{\colorbox{saffron}{Area - length×breadth}}$

‎ ‎

‎ ‎

Area of inner rectangle -

Length = 40m

Breadth 25cm

Area- 40×25

$= {1000m}^{2}$

‎ ‎

‎ ‎

Area of outer rectangle -

Length = 40+2.5= 42.5m

Breadth= 26+2.5= 27.5 m

Area- 42.5×27.5

$= {1168.75m}^{2}$

‎ ‎

‎ ‎

Area of Path -

Area of outer rectangle- Area of inner rectangle

$= {1168.75}^{2} - {1000}^{2} \\ \\ = {168.75m}^{2}$
