A mosaic pattern is an octagon made of a central square of side 10 cm, 4 rectangles (each 10 cm by 4 cm) on its sides and 4 corner right triangles (each with legs 4 cm). Find the total area of the mosaic.

Question

Accepted Answer

292 sq cm. Square = 10 x 10 = 100. Four rectangles = 4 x (10 x 4) = 160. Four triangles = 4 x 1/2(4)(4) = 4 x 8 = 32. Total = 100 + 160 + 32 = 292 sq cm.
