the perimeter of a rectangle is 38 inches

By Allen Kazadi

The length of a rectangle is 4 inches more than twice the width. If the perimeter of the rectangle is 38 inches, what is the length?

Answer:

2X+4)+(2X+4)+X+X=38

Lets add our X’s and then add our whole numbers. 6X+8=38

Lets work our sentence by subtracting 8 from each side of the equal sign.

6X+8–8=38–8

6X=30

Lets divide each side by 6.

6X/6=30/6

X=5 now lets prove 5 is X.

(2×5+4)+(2×5+4)+5+5=38

(14)+(14)+5+5=38

28+10=38

38=38

X is equal to 5.
