Answer:

Equation: 8.3+8.3+3.8+x=24.4

Unknown Side Length: 4 inches

Explanation:

We know that the perimeter is 24.2 in. and there is 4 sides for this shape.

We already know 3 sides, so we can set up an equation.

8.3+8.3+3.8+x=24.4

We can start solving the equation.

Combine like terms.

20.4+x=24.4

Subtract 20.4 on both sides.

x=24.4-20.4

x=4
