In which quadrant does the solution of the system fall? y=x-1, y=-3x-5

Solve the 2 equations then if : X and Y are positive then it is the first quad
if X is negative and Y is positive then it is in second quad
if X is negative and Y is negative then it is 3rd quad
if X is positive and Y is negative then it is the 4th quad
(look at the signs of numbers solved by the equation)

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
