Answer:
40cm^2
Step-by-step explanation:
A=a+b/2×h
A=6+10/2*5
A=16cm/2*5cm
A=8cm*5cm
A=40cm^2

Those two quantities cannot be added.
In order to add or subtract quantities, they don't necessarily both need to
have the same units, but both must have the same physical dimensions
so that one unit can be converted to be the same as the other unit.
"Physical dimensions" are things like mass, length, area, volume, time,
force, speed, etc.
In this problem, one quantity has the unit 'kg'so its physical dimension is <em><u>mass</u></em>.
The other quantity has the unit 'km' so its physical dimension is <em><u>length</u></em>. Obviously
these physical dimensions are different, so there's no way that either unit can be
converted to match the other one, and the quantities can't be added.
Poster standard dimension: 8.5 inches by 11 inches
Both length and width of the poster may vary 1/20%
∴ length and width may vary 1/20 % = 0.05% = 0.0005
∵ Area = Width * Length
∴ Area = 8.5 * 11 = 93.5 in²
Smallest acceptable area for one poster:
Width: 8.5 * (1 - 0.0005) = 8.49575 in.
Length: 11 * (1 - 0.0005) = 10.9945 in.
∴ The smallest area = 8.49575 * 10.9945 = 93.4065 ≈ 93.407 in².
