Answer:

the answer for the fifth side would be 9 inches.

Step-by-step explanation:

if you know that two sides are 5 inches long and the other two sides are 4 inches long then add 5+5+4+4 which equals 18 so then subtract 27 from 18 and you get 9 which is the length of the last side. 9 inches. I hope this helps

Answer:

9 in

Step-by-step explanation:

The sum of the five sides = 27 in

We know that 2 sides are 5 in and 2 sides are 4 in

Let x be the length of the fifth (unknown) side

Therefore, 5 + 5 + 4 + 4 + x = 27

Combine like terms:  18 + x = 27

Subtract 18 from both sides:  x = 9

Therefore, the fifth (unknown) side is 9 in long
