A) 7.0 in. B) 11.9 in. C) 9.9 in. D) 14.0 in.

base *height*1/2=A x*x*1/2=49

Before you solve for x, you need to simplify the equation, which becomes x^2*1/2=49.

To solve for x, you would use order of operations, and multiply by sides by 2, which makes x^2=98. To find x, you find the square root of both sides, which gives you x= square root of 98. The square root of 98 is about 9.9, so 9.9 is your answer

$\frac{x^2}{2}=49$$x=7 \sqrt{2}$
