Question

Elena has eight rods, each of length 10 cm, correct to the nearest centimeter. She places them in the shape of a rectangle, three rods long and one rod wide. What is the perimeter of the rectangle? Option 1: 30 cm Option 2: 32 cm Option 3: 34 cm Option 4: 36 cm

Answer 1

The perimeter of the rectangle is 32 cm.

Step-by-step explanation:

The perimeter of a rectangle is found by adding up the lengths of all its sides. In this case, the rectangle has three sides of length 10 cm and one side of length 10 cm. So, the perimeter is 10 cm + 10 cm + 10 cm + 10 cm = 40 cm. However, the question states that the lengths are correct to the nearest centimeter, so we round 40 cm to the nearest centimeter, which is 40 cm. Therefore, the correct answer is Option 2: 32 cm.
