Dimensions 6201

Mr. John's plot of land has dimensions of 252 dm and 28 m. How far apart must he place the fence posts, so they are the same distance on both sides? How many will he need to fence the entire property?

Correct answer:

x =  28 dm
n =  38

Step-by-step explanation:

a=252 dm b=28 10=280 dm  252=22327 280=2357 GCD(252,280)=227=28  x=GCD(a,b)=GCD(252,280)=28 dm
o=2 (a+b)=2 (252+280)=1064 dm n=o/x=1064/28=38
