Uma sala com formato de trapézio, determine uma área dessa sala.
1 answer:
The image of the room is in the attachment.
Answer: (c) 12.8 m²
Step-by-step explanation:
The area of a trapeze is calculated as:
A =
where:
B is bigger side
b is smaller side
h is height of trapeze
From the image, we have:
B = 3.8m
b = 2.6m
h = 4m
A =
A = (3.8+2.6).2
A = 12.8
The area of the trapeze is A = 12.8 m².

Given:
A line passes through the points (2,-1) and (1,-5).
To find:
The equation of the line.
Solution:
If a line passes through the two points, then the equation of the line is
The line passes through the points (2,-1) and (1,-5). So, the equation of the line is
Using distributive property, we get
Subtract 1 from both sides.
Therefore, the correct option is B.
