Perimeter of rectangular figure is given by:
Perimeter = 2( l+ w)...............(1)
where l and w are length and width of rectangle.
We are given perimeter = 454 yards......................(2)
We are also given length is 5 yards less than triple the width.
So we have length = 3w-5....................(3)
Plugging the values of P and l from (2) and (3) in (1)
![454 = 2( w + 3w-5)](https://tex.z-dn.net/?f=%20454%20%3D%202%28%20w%20%2B%203w-5%29%20)
![454 = 2( 4w-5)](https://tex.z-dn.net/?f=%20454%20%3D%202%28%204w-5%29%20)
dividing both sides by 2 ,
![227= 4w-5](https://tex.z-dn.net/?f=%20227%3D%204w-5%20)
adding 5 on the left side,
![232= 4w](https://tex.z-dn.net/?f=%20232%3D%204w%20)
dividing both sides by 4
w=58
Plugging this value in equation (3) to get length,
![l=3w-5 = 3(58) -5= 169](https://tex.z-dn.net/?f=%20l%3D3w-5%20%3D%203%2858%29%20-5%3D%20169%20)
Answer:
Length is 169 yards and width is 58 yards.
