The nyc parks department is designing a rectangular athletic field for a new park in brooklyn. the width of the field needs to be 10 feet shorter than the length, and the perimeter of the field needs to be 80 feet. what is the length of the new field?

Length = 25feets

Step-by-step explanation:

Let the length l = x

Width w = x - 10

Perimeter = 80

And Perimeter = 2(l + w)

:- 80 = 2{x + (x - 10)}

80 = 2{x + x - 10}

80 = 2(2x - 10)

80 = 4x - 20

4x = 80 + 20

4x = 100

x = 100/4

x = 25ft

step-by-step explanation:

hj=3x+20

ji=15x-64

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
