Question 642256: the parallel sides of a trapezium are a and b respectively. find the value of a + b if it has a area of 20cm2 and the distance between the parallel sides is 5cm.
1/2(a+b)(5)=20
i do not understand the next step
a+b=20 x 2 + 5

Question 694176: If you can not answer all of my question it is fine but i would like some help on these problems:
The choices for the answer are True or False:
1.If three points are collinear, then they are coplanar
2.Any two points are collinear
3.Given two points, there is more than one plane containing them
4. The bisector of the vertex angle of an isosceles triangle bisects the base and is perependicular to the base
5. The base angles of an isosceles triangle are acute
6. An altitude of a triangle lies in the interior of the triangle
7. If three triangles have unequal measures, then no two sides of the triangle are congruent
8. Every right angle has two acute angles
9. The longest side of any triangle is called the hypotenuse
10. The median of a triangle bisects the side to which its drawn
11. Each side of an angle is a ray
12. The diagonals of a square are perpendicular to each other.
Thanks
