Question

A rectangle has a perimeter of 44 centimeters. The width is 10 centimeters. What is the length of the rectangle? o 12 centimeters O 20 centimeters 0 24 centimeters O 34 centimeters

Answer 1

12 centimeters

Step-by-step explanation:

We can call the length of the rectangle x.

Then, the perimeter of a rectangle is 2 times the length added to 2 times the width. Since the width is 10 cm, we get:

Perimeter = 2x + 2(10)

Perimeter = 2x + 20

Additionally, we know that the perimeter is 44 cm, so

44 = 2x + 20

Now, we can solve the equation for x

44 - 20 = 2x + 20 - 20

24 = 2x

24/2 = 2x/2

12 = x

Therefore, the length of the rectangle is 12 centimeters.
