Question

A lawn 120 m by 80 m is surrounded by a path of 3 m width. The area (in m${}^2$) of the path is

• A. 1164
• B. 1236
• C. 8364
• D. 10836

Answer 1

Answer: (B)

1236

Area of the lawn=$120\times 80=9600m^2$

Length of the outer rectangle=$120+3+3=126m$

Breadth of the outer rectangle$=80+3+3=86m$

Area of the outer rectangle=$126\times 86=10836m^2$

$\therefore$Area of the path$=10836-9600=1236m^2$
