Test Of Essential Academic Skills (TEAS) ATI Mathematics Practice Test

If a rectangle has a length of 10 cm and a width of 5 cm, what is its perimeter?

15 cm 30 cm 40 cm 50 cm

Correct Answer:

40 cm

Explanation:

To find the perimeter of a rectangle, you can use the formula: Perimeter = 2 × (Length + Width) In this case, the length is 10 cm and the width is 5 cm. Plugging these values into the formula gives: Perimeter = 2 × (10 cm + 5 cm) Perimeter = 2 × (15 cm) Perimeter = 30 cm Thus, the perimeter of the rectangle is 30 cm, making it the correct answer. This calculation shows how both the length and width contribute to the total distance around the rectangle, which is essential for understanding perimeter.
