A rectangular park has a perimeter Of 12 miles it is 4 miles wide what is the area of the park

A =  8 miles^2

Step-by-step explanation:

The perimeter of a rectangle is given by

P = 2(l+w)

Substitute the knowns in

12 = 2(l+4)

Divide each side by 2

12/2 = 2/2(l+4)

6 = l+4

Subtract 4 from each side

6-4 = l+4-4

2 =l

The length is 2 and the width is 4

We want to find the area

A = l*w

  = 2miles * 4 miles

   = 8 miles^2
