Question

find the perimeter of the following polygon in these sorts of junk food the correct unit in your answer

Answer 1

Solution

Given a trapezoid with the following dimensions

$10ft,10ft,11ft,15ft$

To find the perimeter, P, of the polygon, we add up all the side lengths i.e the formula to find the perimeter, P, of the trapezoid is

$\begin{gathered} P=a+b+c+d \\ \text{Where a, b, c and d are the side lengths} \end{gathered}$

Where

$\begin{gathered} a=10ft \\ b=10ft \\ c=11ft \\ d=15ft \end{gathered}$

Subsitute the values into the formula above

$\begin{gathered} P=10+10+11+15=46 \\ P=46ft \end{gathered}$

Hence, the perimeter is 46ft
