5: A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 89m long and 53m wide. What is the length of a training track running around a field? (use the value 3.14 for pie and do not round your answer)

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

y -5 = (-1/4)(x + 8)
