Question

Stephanie walks 3 rounds around a triangular park whose dimensions are 4.5 yd, 3 yd, and 5 yd.
What is the total distance that she walks?

Answer 1

We know that in the given triangular park:
Length of the first side = 4.5 yd
Length of the second side = 3 yd
Length of the third side = 5 yd

The total distance that Stephanie has covered would be 3 times the perimeter of the park.

$\text{Perimeter =}Lengthofthefirstside+Lengthofthesecondside+Lengthofthethirdside$
$\Rightarrow 4.5+3+5=12.5yd$

$\text{Distance covered by Stephanie =}$
$3\times Perimeter=3\times 12.5=37.5yd$

Hence, Stephanie walks 37.5 yards.
