Question

Determine the perimeter of the athletic track

Answer 1

418.2477796 m

Explanation:

You divide it in to a rectangle and 2 half circles (which will make a whole circle if added together) and solve them.

• RECTANGLE

P= 2( L + W) - - > 2 ( 102 + 60)= 324

• Circle (has a circumference not a perimeter)

Cf= 2лr^2 - - - > 2л(30)^2=30л

• Together

324 + 30л = 418.2477796 m
