A ceramic tile is 1 cm long on each edge.What is the area of a counter top that istiled with 2 of these ceramic tiles? ?  cm2iT11aA ceramic tile is 1 cm long on each edge.What is the area of a counter top that istiled with 2 of these ceramic tiles?Use the formula for the area of a square,A = s2.pThe side of each tile is 1 cm.5A = 126 = 3The area of each tile is 3 cm2. However, thereare 2 tiles on the counter top.Multiply the area of each tile by 2.p3 x 2 = 4pThe area of the tiled counter top is 4 cm2.
