Question 36 [Case Based] A tiling or tessellation of a flat surface is the covering of a plane using one or more geometric shapes, called tiles, with no overlaps and no gaps. Historically, tessellations were used in ancient Rome and in Islamic art. You may find tessellation patterns on floors, walls, paintings etc. Shown below is a tiled floor in the archaeological Museum of Seville, made using squares, triangles and hexagons.A craftsman thought of making a floor pattern after being inspired by the above design. To ensure accuracy in his work, he made the pattern on the Cartesian plane. He used regular octagons, squares and triangles for his floor tessellation patternUse the above figure to answer the questions that follow: Question 36 (i) What is the length of the line segment joining points B and F? Here, B = (1, 2) F = (−2, 9) Now, BF = √((𝑥2 −𝑥1)2+(𝑦2 −𝑦1)2) = √(( −2 −1)2+(9 −2)2) = √((−3)2+(7)2) = √((3)2+(7)2) = √(9+49) = √𝟓𝟖 units
