Question

The perimeter of the rectangle below is 102 ft. What is the value of X

Answer 1

Answer:

X=46 ft.

Step-by-step explanation:

Write an equation to solve the problem.

Since one side is 3 ft, don’t forget that there is another side of the rectangle that is also 3 ft. We can add this part to the equation as 2(3).

Now, let’s see the other side. It’s (2+x) ft. As mentioned before, there are another side, so, you guessed it: 2(2+x).

We have our equation:

2(3)+2(2+x) = 102 ft.

Simplify first:

6+4+2x = 102 ft.

10+2x=102 ft.

2x=92 ft.

x=46 ft.
