Question

The length and breadth of a rectangular park are 30 m and 20 m respectively. A path 4 m wide run lengthwise one side of park. The area of the path is----

• A. $100$ $m^2$
• B. $120$ $m^2$
• C. $80$ $m^2$
• D. $40$ $m^2$

Answer 1

Answer: (B)

$120$ $m^2$

Let $ABCD$ be the park and PQRS be the path laid lengthwise.

Length of the path $=30m$

Breadth of the path$=4m$

$\therefore$ Area of the path = Length $\times$ Breadth

$=30$ m $\times$ $4$ m

$=120$ $m^2$

Hence, the area of the path is $120$ $m^2$
