  11. Pyramid Trapezoid Ulun Danu Temple consist of trapezoids and pyramid

  12. Trapezoid • Trapezoid is a quadrilateral which has one pair of parallel side. • AB and CD is parallel. • AD and BC are hypotenuse. b a

  13. Formula The surface area of trapezoid b t Surface Area Height The Parallel Side a

  14. 3 m • One trapezoid of Ulun Danu Temple at the bottom side has AB = 5 m, CD = 3 m and hypotenuse = 2m. • The surface area of one trapezoid is 2 m 2 m t 2 m 1 m 1 m 1 m 5 m C D A B

  15. The surface area of trpezoid 3 m 2 m 2 m 1 m 1 m 5 m Because there are 4 trapezoid in the bottom of Ulun Danu Temple, so the surface area of 4 trapezoid is
