document.write( "Question 1174572: Diana wants to create a rectangular chocolate bar for their mini sweets store for her friend, Daisy, and for her treatment. She plans on making 500 chocolate bars that she wants to sell at $5 each. Given that the dimension of each chocolate bars are (6d+9) cm. and (4d+1) cm. in terms of length and width, respectively, and the bar's total perimeter is 278 cm. Find the value of d, the area of 1 chocolate bar, and the length of its diagonals(diagonals can be name randomly). \n" ); document.write( "
