Perhatikan gambar berikut.Luas layang layang tersebut adalah....

[tex] = {25}^{2} = {15}^{2} + {x}^{2} \\ = 625 = 225 + {x}^{2} \\ = 625 - 225 = {x}^{2} \\ = 400 = {x}^{2} \\ = \sqrt{400} = x \\ =20 [/tex]
[tex] = {17}^{2} = {15}^{2} + {x}^{2} \\ = 289 = 225 + {x}^{2} \\ = 289 - 225 = {x}^{2} \\ = 64 = {x}^{2} \\ = \sqrt{64} = x \\ = 8[/tex]
