Hi Paul, To solve this problem and the other two you sent us you need to read the question carefully and translate the English statements into mathematical equations. Consider this question.
The length and width of the rectangle are the important dimensions so I am going to give them names. let the length of the rectangle be x feet and the width y feet, x > y. The area is then xy square feet. According to the instructions you construct a new rectangle with width 2 feet shorter than y and length 3 feet longer than x. Thus the new rectangle is y - 2 feet by x + 3 feet. You are also told that one of these dimensions is 6/5 times the other. But 6/5 > 1 and x + 3 > y - 2 and hence it must be that
The area of the new rectangle is (x + 3)(y - 2) square feet which we are told is 250 square feet larger than the original rectangle. Thus
Solve these two equations for x and y. I hope this helps, | ||||||||||||
