Question

Anthony ran 3 rounds of a square ground of side 10 m. Determine the total distance he ran.

• A. $30$ m
• B. $60$ m
• C. $90$ m
• D. $120$ m

Answer 1

The correct option is D $120$ m

Step 1: $\text{Distance covered in 1 round of the square ground}$
$\text{= Perimeter of the square ground}$
$=10+10+10+10$
$=40$ m

Step 2: Distance covered in 3 rounds of the square ground
$=3\times 40$
$=120$ m

Anthony ran a total distance of $120$ m.
Hence, option(d.) is the correct choice.
