Boye cuts out a rectangle that has a perimeter of 26 inches and a length of 8 inches. He cuts out another rectangle that is the same length and twice as wide.

What is the perimeter of the new rectangle?

Let's assume the width of the rectangle that Boye cuts out is "w" inches.

The perimeter of a rectangle is given by the formula P = 2l + 2w, where "l" is the length and "w" is the width.

Given that the length of the rectangle is 8 inches and the perimeter is 26 inches, we can set up the equation:

26 = 2(8) + 2w

Simplifying this equation gives us:

26 = 16 + 2w

Subtracting 16 from both sides, we have:

10 = 2w

Dividing both sides by 2, we get:

5 = w

So the width of the rectangle Boye cuts out is 5 inches.

Now let's find the dimensions of the new rectangle. The length remains the same at 8 inches, and the width is twice as wide as the original rectangle, so it is 2 * 5 = 10 inches.

The perimeter of the new rectangle is given by the formula P = 2l + 2w:

P = 2(8) + 2(10) = 16 + 20 = 36

Therefore, the perimeter of the new rectangle is 36 inches.
