Answer:

x = 12 ft

Explanation:

We know that by adding up all of the values of the sides, we will get the value of the perimeter. Using this information, we can set up an equation and simplify to find the variable.

16 + 20 + x + x = 60 <----- The sum of the sides is the perimeter

16 + 20 + 2x = 60 <------ Combine variables (x + x = 2x)

36 + 2x = 60 <----- Add 16 and 20

2x = 24 <----- Subtract 36 from both sides

x = 12 <----- Divide both sides by 2

Answer:

x=12

Explanation:


16+20+2x=60\\36+2x=60\\2x=24\\x=12

the perimeter is the side lengths added together meaning it is


16+20+x+x=60. x+x can be simplified to 2x. now solve for x
