With this information, options a, c, d and e have a mode of nine
x=4, because 10+(4*2)=10+8=18 and since it is a rectangle the sides are the same.
The answer is 50. First, you need to multiply 34.6 by 34.6, and multiply 15.4 by 15.4, and subtract the products which gives you 960. Next you subtract 15.4 from 34.6, giving you 19.2. Lastly, you divide 19.2 into 960 and you get 50.
