Question

A rectangle has a length that is 3 feet longer than its width. its perimeter is 26 feet. What is the width of the rectangle?

Answer 1

w= x+3
l= x

(you would need to add 3 to the width to make it equal to the length, THAT'S WHY w=x+3 and l=x )

P=2(w+l)

in your case,
26 =2( x + [x+3] )

Solve for x, and then tell me the width (that's equal to x+3, but tell me the width not in terms of x, rather as value)

Answer 2

10?

Answer 3

26 =2( x + [x+3] )
26 =2( 2x+3 )
26 =4x+6
20=4x
x=5

w =x+3=5+3 =8
l =x = 5

Checking:

26=2(8+5)
26=2(13)
26=26

Answer 4

Thanks
