Question

The length of a rectangle is two more than the width. the perimeter is 36cm. write a system of equations that could be used to determine the width and length of this rectangle

Answer 1

If the length is two times its width and its perimeter is 36cm. we can write the following equation
let the width be X.
so the equation will be:
(X + 2X)2=36cm or
2X + 4X=36cm
