Answer 2

Answer: 99.4 m

Step-by-step explanation:

Given:

The area is, $A = 170.2\,\rm{m}^2$

Length of one side is, $x=3.7\,\rm{m}$

Calculate the length of the other side.

$\begin{aligned}A&=xy\\170.2&=3.7y\\y&=\frac{170.2}{3.7}\\&=46\,\rm{m}\end{aligend}$

Calculate the perimeter.

$\begin{aligned}P&=2(x+y)\\&=2(3.7+46)\\&=2(49.7)\\&=99.4\,\rm{m}\end{aligned}$
