This parallelogram covers 40 cm².

  • A rectangle with the same area would be a 6.32 cm square, just for scale.
  • The perpendicular height (the straight gap between the two parallel bases) is 5 cm.
  • Area is simply base times perpendicular height. The slant of the sides never changes it.

Next stepIf you only know the slanted side and the interior angle, switch to the "two sides and angle" method above.
