After the Spring Festival, Fangfang’s store needs to be renovated. Dad ordered a batch of square floor tiles. If they are assembled into a rectangle with a ratio of length to width of 5:4, there will be 38 pieces left; Large rectangle, less 53 faster. Please help Fangfang do the math, how many floor tiles did Dad order?
春节过后，芳芳家的店面要装修，爸爸定了一批正方形地砖，如果拼成一个长与宽之比为5：4的长方形，则余38块；如果改拼成长与宽各增加一块的大长方形，则少53快．请你来帮芳芳算一算，爸爸定了多少块地砖？
