Out of 25+ years of teaching one of my favorite topics
Would need to know a bit more about the parallelogram to solve this problem. Such as is it an isosceles parallelogram (meaning its two non parallel sides are equal) and then you would need either an angle measure or the length of the other base. If you knew those things, you could split the parallelogram up into other geometric figures, such as a rectangle and two equal right triangles.
? Round your answer to the tenths place if necessary.
