The perimeter of a rectangle is 43 inches more than the length of the rectangle. The width is 10 inches. Find the length.
The Length is 23
Let L be Length, your Perimeter P=L+43in. We have the width, so 10+10=20, both sides added.
So here is the equation: P=2w+2L. Now we plug in L+43=20+2L.
L+23=2L subtracted 20
L=23 subtracted L
Your perimeter is 66in also
