- A triangular park has sides 15 m, 18 m and
120 m. Leaving an entrance 2 m wide on one of
its sides, the park has been fenced with barbed
wire. How much length of wire will be needed?​

Answer 1

Answer:

151 m

Step-by-step explanation:

perimeter = side + side + side

p = 15+18+120 =153 m

leaving the entrance = 2 m

hence 153-2 =151 m
