The length of a rectangle is four meters less than the width. the perimeter is 34 meters. find the length and width (in meters).

answer:

length=10meters and width=7 meters

step-by-step explanation:

length=x

width=y

2x+2y=34

2y-4=x

answer:

step-by-step explanation:

length: x-4

width: x

perimeter: 34m

since perimeter os length plus width, and there are 2 of each, you add the equation twice and equate it to 34m:

2(x-4)+2(x)=34

2x-8+2x=34

4x-8=34

4x=34+8

x=42÷4

x=10.5
