the area of a trapizoid is 108cm squared the height is 12cm and the length of one parrallel sides is 8cm. find the length of the 2nd parallel side.
.
area of any trapezoid is:
((b1 + b2)/2)h
.
where
b1 is length of one parallel side
b2 is length of opposite parallel side
h is height
.
plugging in what was given:
Let x = length of 2nd parallel side:
108 = ((8 + x)/2)(12)
108 = (8 + x)(6)
18 = (8 + x)
10 cm = x
