Question

the width of a rectangle measures (t - 9u) centimeters, and its length measures (4t - 4u) centimeters whats the perimeter of the rectangle

Answer 1

To find the perimeter of a rectangle, you can use the formula:

Perimeter = 2 * (Length + Width)

In this case, the width of the rectangle is (t - 9u) centimeters, and its length is (4t - 4u) centimeters.

So, the perimeter is:

Perimeter = 2 * ((4t - 4u) + (t - 9u))

Now, let's simplify the expression inside the parentheses:

Perimeter = 2 * (4t - 4u + t - 9u)

Combine like terms:

Perimeter = 2 * (5t - 13u)

Now, distribute the 2:

Perimeter = 10t - 26u

So, the perimeter of the rectangle is 10t - 26u centimeters.
