Question

the area of a trapezoid is 152. the height is 16 and the length of one of the sides is 6. find the length of the second parallel side.

Answer 1

Formula for trapezoid
A=h*(b1+b2)/2,

b1 an db2 are the two lengths of the sides

152 = 16*(b1+6)/2 = 8*(b1+6)=8*b1+48--> 8*b1=104, b1 = 104/8=13

A = 16*(6+13)/2=16*9.5=152
