you're giving the diagram shown and also told don't be decides to be are all 15 centimeters that we want to label them as such. And all of these air squares, of course. Which means that the side things were all the same. And we're also told that G has side lengths of seven centimeters. So we will live with those a seven, Okay? And now we're asked to find the side links of D. And so to do that, we're going to use the information we have in order to find a side exit D. And so first, we're going to see that side. Think of B is 15 okay? And we know that the side life of G is seven. That means that the side length of death has no choice but to be eight. And so, since it is a square, we know that all of its side thinks are going to be eat. Okay, so now we know that. And we know that this side right here is eight. Because we just found the F as I likes of eight. And we know that G over here has silex of seven. That means that I has to have silence of one. Okay? And now we can use that information to find the side life of E. Because the silent B is composed of the side like the F plus aside, like the vie. So a plus one is nine. That means E has so thanks of nine. And now I can use that defy the set to find the side length of D. This I think the D is composed of the siding with E plus deciding that I that's nine plus one and that is 10 meaning all of decides are going to be 10 centimeters. And now if we look at the answers, sure enough, that's an answer. The answer is going to be be 10 cents meters.
