find the perimeter of the figure below. notice that one side length is not given. assume that all intersecting sides meet at right angles. be sure to include the correct unit in your answer.

Answer

Explanation:

Step1: Find the missing vertical side

Since all intersecting sides meet at right - angles, the missing vertical side is $13-(8) = 5$ cm.

Step2: Find the missing horizontal side

The missing horizontal side is $10 - 4=6$ cm.

Step3: Calculate the perimeter

Perimeter is the sum of all side - lengths. $P=4 + 8+5+6 + 5+13+10$ $P=(4 + 6)+(8 + 5)+(5 + 13)+10$ $P = 10+13+18+10$ $P=51$ cm

Answer:

$51$ cm
