Question

Write an expression to model the perimeter of a football field if the length of a football field is three-fourths the width of the football field. (With steps)

Answer 1

Perimeter = width*7/2

Explanation:

Perimeter = 2(length + width)

In this case:

length = width*3/4

Then:

Perimeter = 2((width*3/4) + width)

Perimeter = 2 ((widt*3/4) + (width4*4))

Perimeter = 2(width*7/4)

Perimeter = width*14/4

Perimeter = width*7/2
