The perimeter of a football field is 920 feet. The width is 60 feet more than one-third of the length. What are the dimensions o
Step2247 [10]

Given:

Perimeter of a football field = 920 feet.

The width is 60 feet more than one-third of the length.

To find:

The dimensions of a football field.

Solution:

Let the length of the field be x.

Then, width = \dfrac{1}{3}x+60

We know that,

Perimeter = 2( length + width)

920 = 2(x+\dfrac{1}{3}x+60)

920 = 2(\dfrac{4}{3}x+60)

920 =\dfrac{8}{3}x+120

Subtract both sides by 120.

920-120 =\dfrac{8}{3}x+120-120

800 =\dfrac{8}{3}x

Multiply both sides by 3.

2400 =8x

Divide both sides by 8.

300 =x

Now,

Length = 300\text{ feet}

Width=\dfrac{1}{3}(300)+60

Width=100+60

Width=160\text{ feet}

Therefore, the length and width of the football field are 300 feet and 160 feet respectively.
