so the ratio of the side with the length 5 to the side <em>a</em> is 1:2(or we could say a to 2a). Because of this we now multiply 2 to 5 to get a=10(because it is a 1 to 2 ratio).The relation between the side worth 2 and the side <em>c</em> is a√2 to a. so we divide √2 from 2 to get √2 and this number in decimal form is 1.41421356237....., so rounded to the nearest tenth is 1.4(because 1 rounds down)
