A path goes around a triangular park, as shown.


a. Find the distance around the park to the nearest yard.
( I counted and got 190 that's not correct)
b. A new path and a bridge are constructed from point Q to the midpoint M of PR.
Find QM to the nearest yard.
(I counted and got 30 also not correct)

Answer:

Explanation:

the two sides are 50 and 80

Use Pythagorean theorem

It’s about 94.34 (94)

So I’d guess 224

a. The distance around the park to the nearest yard is equal to 191 yards.

b. Since a new path and a bridge are constructed from point Q to the midpoint M of PR, the length of QM is 40 yards.

Part a.

In Mathematics and Geometry, Pythagorean theorem is an Euclidean postulate that can be modeled or represented by the following mathematical equation:


c^2=a^2+b^2

Where:

  • a is the opposite side of a right-angled triangle.
  • b is the adjacent side of a right-angled triangle.
  • c is the hypotenuse of a right-angled triangle.

In order to determine the distance around the park, we would have to apply Pythagorean's theorem as follows;


PR^2=PQ^2+QR^2\\\\PR^2=40^2+70^2\\\\PR^2=1600+4900\\\\PR=√(6500)

PR = 80.6226 ≈ 81 yards.

Total distance (perimeter of triangle PQR) = PQ + QR + PR

Total distance (perimeter of triangle PQR) = 40 + 70 + 81

Total distance (perimeter of triangle PQR) = 191 yards.

Part b.

Since triangle PQR is a right-angled triangle and based on the definition of a midpoint, we have;

QM = 1/2 × PR

QM = 1/2 × 80.6226

QM = 40.3113 ≈ 40 yards.
