Question

What is the perimeter of STUV?* STUV – XYZW T Z 20

Answer 1

The perimeter of the figure is the addition of the segments so in this case we have to find the sides so:

$\frac{35}{21}=\frac{25}{TU}=\frac{20}{UV}=\frac{20}{SV}$

So:

$\begin{gathered} TU=\frac{25\cdot21}{35}=15 \\ UV=\frac{20\cdot21}{35}=12 \\ SV=\frac{20\cdot21}{35}=12 \end{gathered}$

So the perimeter will be:

$\begin{gathered} P=21+15+12+12 \\ P=60 \end{gathered}$
