A rectangle is 3 feet longer than it is wide. If the perimeter is
30 feet, find the area in square feet.

A= 54 ft^2

Step-by-step explanation:

3+w= length

w=width

(3+w) + (3+w) + w + w = 30

6+ 4w=30

4w=24

w=6

width= 6

length= 3+6=9

area= l x w

9 x 6 =54

hope this helped!

it has the same slope and a different y-intercept

hope this : )
