Step-by-step explanation:
length of each rectangle= 9 1/14=127/14
breadth of each rectangle=5=4 1/2= 9/2
so perimeter of 1 rectangle= 2(l+r)
=2(127/14+ 9/2)
=2(127+63)/14
=2×190/14
=190/7
=27.14 feet
so total length of fencing= 4×27.14
=108.57 feet
hope you understand the solution and good luck!!
Distance = 475 time = 9.5 hrs since distance and time varies directly therefore in 9.5 hrs train travels 475 miles => In 1 hr train travels 475 / 9.5 miles = 50 miles and in 4 hrs train travells 50*4 i.e 200 miles
3n+4=32÷2
3n+4=16
subtract 4 from both sides
3n=12
divide both sides by 3
n=4
