In trapezoid, two triangles are formed by the bases and the intersecting diagonal segments. the areas of these triangles are s1 and s2. find area of the trapezoid in terms of s1 and s2.

Since we know that we can find area of a trapezoid by dividing our trapezoid into two triangles with parallel sides of trapezoid as bases of our triangles. The area of trapezoid is sum of the areas of these two triangles.

We have been given that areas of our triangles are and . We can find area of our trapezoid by adding areas of our both triangles.    

Therefore, area of our trapezoid will be .  

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
