Question 69020: a piece of wire is shaped to enclose a square, whose area is 121sq. in. it is then reshaped to enclose a retangle whose length is 13in. What is the area of the retangle in square inches? Answer by ptaylor(2198) (Show Source):
You can put this solution on YOUR website! Let x= length of wire (in inches)
Length of one side of square would be 0.25x in
Area of square is: and this equals 121 sq in--So:
take sqrt of both sides inches---------------------------------length of wire
Now 44 inches minus 2 times the length of the rectangle must equal 2 times the width of the rectangle
inches
Length of rectangle = inches
Area of rectangle = sq in----------------------------------answer
