    or you could draw the extra line as above and find the area of the whole rectangle = 7 *12 then subtract 2 * area of one of the unshaded rectangle ( each = 5 * 6)

    Is it 21? I multiplied 2 * 2 since there were 2 unshaded parts and then divided 84 by 4 and got 21

    no the area of one unshaded part = 5*6 so area of 2 = ?
