Question

Brianna walks around a triangular park, daily. The longest side of the park measures 75 yards
and the shortest side measures 45 yards. If she walks 3 full laps around the park, how far does she
walk in one day?

Answers

  1. She walks 540 yards for 3 full laps around the park per day.

    How to determine the distance

    From the information given;
    The longest part of the triangular park = 75 yards
    The shortest part = 45 yards
    Let’s find the other part, using Pythagorean theorem;
    a² = b² + c²
    75² = 45² + c²
    c² = 75² – 45²
    Find the squares
    c² = 5625 – 2025
    c² = 3600
    Make ‘c’ the subject
    c = √3600
    c = 60 yards
    If she walks
    75 + 60 + 45 yards per lap
    180 yards per lap
    For three laps, she walks
    = 3 × 180
    = 540 yards
    Thus, she walks 540 yards for 3 full laps around the park per day.
