**Reiny**, Monday, November 9, 2009 at 8:27am"A trapezoid has a lower base which is twice as long as its parallel upper base. The upper base is 21 cm long"

Doesn't that make the two parallel sides 21 and 42 cm?

"One non-parallel side is 20 cm long and the other non-parallel side is 6 cm longer than the shorter non-parallel side"

Doesn't that make the other two sides 20 and 26 cm?

Isn't perimeter the sum of the sides ?
