Answer:
Area = 260 cm²
Step-by-step explanation:
Area of parallelogram = base × height
Base = 20 cm
Height = 13 cm
Plug in the values
Area of parallelogram = 20 × 13
Area = 260 cm²
Answer: Deductive reasoning does not work if the premises in which they are based are wrong or if the deduction is not based on any premises given.
Step-by-step explanation: Deductive reasoning works when we make logical assumptions or links between some given premises that are supposed to be true. One example could be assuming that all police officers work with guns, they work wearing a blue uniform and they use a black and white car. If a situation in which a person works in a blue uniform, using a black and white car and a gun is given, one can infer that this person is a police officer. But, if the premise that they work using guns is not always true, for example, you cannot say that this person is a police officer. This happens because the premise given is wrong. If one simply infers that the person in the example is a firefighter, without any logical assumptions, then it doesn't follow the deduction reasoning method.

Answer: the length of the base is 15 kilometers.
Step-by-step explanation:
formula : Area of parrallelogram = Length of base x height
Given: Area of parallelogram = 300 square kilometers
height = 20 kilometers
Substituting values in the formula , we get
300 = Length of base x 20
Length of base = 
= 15 kilometers
Hence, the length of the base is 15 kilometers.
