A pentagonal tile is split by a diagonal into a trapezium and a triangle. The trapezium has parallel sides 10 cm and 20 cm with height 8 cm; the triangle stands on the 20 cm side with height 8 cm. Find the total area of the tile (in sq cm).

Question

Accepted Answer

200. Trapezium = 1/2(10+20)(8) = 1/2(30)(8) = 120 sq cm. Triangle = 1/2(20)(8) = 80 sq cm. Total = 120 + 80 = 200 sq cm.
