Practice Question
Laura walks every evening on the edges of a sports field near her house. The field is in the shape of a rectangle 300 feet (ft) long and 200 ft wide, so 1 lap on the edges of the field is 1,000 ft. She enters through a gate at point G, located exactly halfway along the length of the field.
Laura counts the number of strides she takes during her daily walks. She takes about 80 strides to walk the width of the field from Z to W. Assuming that her stride length does not change, about how many strides does Laura take to walk all the way around the edge of the field?

Answer Choices
- A: 267
- B: 320
- C: 450
- D: 400
Correct Answer: D
Rationale: Perimeter = 1000 ft. Width = 200 ft, 80 strides. Stride length = 200 / 80 = 2.5 ft. Strides for 1000 ft: 1000 / 2.5 = 400. Thus, the correct answer is 400.
