Solution

Solution:

Given:
Length of the park, $l = 120 m$
Breadth of the park, $b = 80 m$
Number of laps around the park, $n = 3$
Perimeter of the park, $P = 2 \times (l + b)$
$\Rightarrow P = 2 \times (120 m + 80 m)$
$\Rightarrow P = 400 m$

[1 mark]

Total distance covered by Paul,
$D =$ (Number of laps) $\times$ (Perimeter of the park)
$\Rightarrow D = n \times P$
$\Rightarrow D = 3 \times 200 m$
$\Rightarrow D = 600 m$
Hence, the total distance covered by Paul would be $600 m$ .
