Answer:

30 units²

Step-by-step explanation:

this ones kinda tricky but basically you need to dilate it all by 2 (to make the figure twice as big)

technically, it would be 7.5 units bc but bc of the dilation it'd be 30

Answer:

$7.5\:\text{square units}$

Step-by-step explanation:

The area of a trapezoid is given by the average of the bases multiplied by the height.

What we're given:

Height of 3
Bases of 1 and 4

The average of the bases 1 and 4 is equal to $\frac{4+1}{2}=\frac{5}{2}=2.5$

Therefore, the area of the trapezoid is $2.5\cdot 3=\boxed{7.5\:\text{square units}}$

Answer:

Reading bar graphs (multi-step) In a bar graph each bar represents a number. The following bar graph shows the number of seconds that different rides last at the fair. We can tell how long each ride lasts by matching the bar for that ride to the number it lines up with on the left.

Here is an example:
