here height h =10cm
base b =24cm
area of two right angle triangle 2*((1/2)bh)
ie b*h
here "b" will be 14 in both triangles so the area will be 10*14=140cm^2
area of square will be 100cm^2 because one side of square is 10cm
total area is 140+100=240cm^2
number of tile required to cover the floor = 15360/240
answer is 64
