hai there :)
The lateral area = surface area not including the bases.
To find the lateral area we need to add up the area of all thoes sides
The 2 bases are the same area and defined by the length and width
That leaves the 2 sides defined by length and height plus the 2 defined by length and height
14 x 6 = 84(length x width)
9 x 6 = 54
2 x 84 + 2 x 54= 276m^2
