Answer:
Decreased by 40%!
Step-by-step explanation:
At first it goes down by 10%, then 30%, so you just add them together and get decreased by 40%.
Lateral area = surface area <em>not including</em> the bases.
To find this area we just need to add up the area of all of those 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 width and height.
Of course, to find the area of a rectangle, we just multiply together its two dimensions.
length × height = 14 × 6 = 84
width × height = 9 × 6 = 54
2 × 84 + 2 × 54 = 276 m²
