Question 976740
The area of a trapezoid is 187 cm squared. The height is 22 cm and the length of one of the parallel side is 6 cm. Find the length of the other parallel side.
***
area of a trapezoid=h/2(a+b), h=height, a=one of the parallel sides, b=other parallel side
(22/2)(a+6)=187
11a+66=187
11a=121
a=11
length of the other parallel side=11
