Question

Uma sala com formato de trapézio, determine uma área dessa sala.

Answer 1

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 = $\frac{(B+b)h}{2}$

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 = $\frac{(3.8+2.6)4}{2}$

A = (3.8+2.6).2

A = 12.8

The area of the trapeze is A = 12.8 m².
