Answer:
286cm²
Step-by-step explanation:
Let the parallel sides be 12cm and 10cm
Height h = 26cm
Area of a trapezium = 1/2(a+b) * h
Area of a trapezium = 1/2(12+10)* 26
Area of a trapezium = 1/2(22)*26
Area of a trapezium = 11 * 26
Area of a trapezium = 286cm²
Hence the area of the tiles is 286cm²
._ is the tenths place . Therefore the answer is 2.8
