The perimeter of a rectangle is 34 units its width is 6.5 Units Write an equation to determine the length(l) of the rectangle.

Length=10.5

Step-by-step explanation: P=34 and W=6.5. This can also be known as Perimeter=W+L+W+L=2(W+L). In this case, it would be 34= 2(6.5 +L). 34=13+2L.(The 2L's are crossed out now because they cancel both out)

 -2L         -2L   (There is a line going down at the equal sign.

34+-2L=13 Subtract 34 from both sides and cancel the two 34's out)

-34        -34

-2L=-21 (Divide both sides by -2) (Cancel out the -2's)

 /-2  /-2

L = 10.5

e) none of the above because the measure of angle cba is 101°

x-3y=4
