The area of a rectangle is 42 ft2 , and the length of the rectangle is 11 ft less than three times the width. find the dimensions of the rectangle.

So if the area is 42 and the length is 11ft less than 3 times than the width then the length is 7 and the width is 6, i think

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
