Re: jest prostokąt
We can begin by using the fact that similar figures have proportional side lengths. Let the length of one side of the new rectangle be x cm. Since the new rectangle is similar to the original rectangle, we can write: {x\over2} = {x + 7\over7} We can solve for x by cross-multiplying: 7x = 2(x + 7)\\...
