Triangular 29781

A triangular building plot is drawn on a 1:5,000 scale plan as a triangle with sides of lengths 32.5 mm, 23.5 mm, and 36 mm. Determine how many m of mesh are needed to fence the entire plot.

Correct answer:

x =  460 m

Step-by-step explanation:

M=5000 a=32.5 mm m=32.5:1000  m=0.0325 m b=23.5 mm m=23.5:1000  m=0.0235 m c=36 mm m=36:1000  m=0.036 m  o=a+b+c=0.0325+0.0235+0.036=25023=0.092 m  x=M o=5000 0.092=460 m
